API to interact with CHT Applications

Settings

Get and update the app settings.

GET /api/v1/settings

Returns the settings in JSON format.

PUT /api/v1/settings

Query Parameters

Returns a JSON object with two fields:

{
  "success": true,
  "upgraded": false
}

Export

Request different types of data in various formats.

Each of the export endpoints except contacts and feedback supports a parameter which returns date formatted in human readable form (ISO 8601). Setting this parameter to false or leaving it out will return dates formatted as an epoch timestamp.

To set this parameter for a GET request use:

http://admin:pass@localhost:5988/api/v2/export/messages?options[humanReadable]=true

To set this parameter for a POST request submit this as the request body:

{
  "options": {
    "humanReadable": true
  }
}

GET /api/v2/export/dhis

Exports target data formatted as a DHIS2 dataValueSet. The data can be filtered to a specific section of the contact hierarchy or for a given time interval.

{
  "filters": {
    "dataSet": "VMuFODsyWaO",
    "date": {
      "from": 949392000000,
    },
    "orgUnit": "KbY9DJ8mBkx"
  }
}

GET /api/v2/export/reports

It uses the search shared library to ensure identical results in the export and the front-end. It also only supports exporting CSV so we can efficiently stream infinitely large exports.

Query parameters

These are identical to the JS objects passed to the shared library, as if you were using it directly in Javascript.

You may either pass JSON in the request body using POST:

POST /api/v2/export/reports
{
  "filters": {
    "forms": {
      "selected": [
        {
          "code": "immunization_visit"
        }
      ]
    }
  }
}

Or using form-style parameters as GET:

GET /api/v2/export/reports?filters[search]=&filters[forms][selected][0][code]=immunization_visit

NB: this API is bound directly to this library. For more information on what queries you can perform with the search library, see its documentation.

GET /api/v2/export/messages

Download messages.

Output

Examples

/api/v2/export/messages

GET /api/v2/export/feedback

Export a file containing the user feedback.

Query Parameters

GET /api/v2/export/contacts

Returns a JSON array of contacts.

Query parameters

These are identical to the JS objects passed to the shared library, as if you were using it directly in Javascript.

You may either pass JSON in the request body using POST:

POST /api/v2/export/contacts
{
  "filters": {
    "search": "jim"
  }
}

Or using form-style parameters as GET:

GET /api/v2/export/contacts?filters[search]=jim

Records can be created one of two ways, parsing the form data yourself and submitting a JSON object or by submitting the raw message string.

Headers

Only one variant of the Content-Type header may be provided; RFC 2616 does not allow multiple content types to appear in a single Content-Type header.

Form Parameters

JSON Properties

Special values reside in the property _meta, so you can’t have a form field named _meta. Only strings and numbers are currently support as field values.

All property names will be lowercased.

Users

All user related requests are limited to users with admin privileges by default.

Supported Properties

Use JSON in the request body to specify user details. Any properties submitted that are not on the list below will be ignored. Any properties not included will be undefined.

Login by SMS

When creating or updating a user, sending a truthy value for the field token_login will enable Login by SMS for this user. This action resets the user’s password to an unknown string and generates a complex 64 character token, that is used to generate a token-login URL. The URL is sent to the user’s phone number by SMS, along with another (configurable) SMS that can contain additional information. Accessing this link, before its expiration time, will log the user in directly - without the need of any other credentials. The link can only be accessed once, the token becomes invalid after being used for one login. The token expires in 24 hours, after which logging in is only possible by either generating a new token, or disabling token_login and manually setting a password.

The SMS messages are stored in a doc of a new type login_token. These docs cannot be viewed as reports from the webapp, and can only be edited by admins, but their messages are visible in the Admin Message Queue page.

To disable login by SMS for a user, update the user sending token_login with a false value. To regenerate the token, update the user sending token_login with a true value.

This feature uses app_settings.app_url and app_settings.token_login to be defined and enabled. If app_settings.app_url is not defined, the generated token-login URL will use the Host request header, which may not always be correct.

POST /api/v1/users

Create new users with a place and a contact.

Creating multiple users at once by passing an array of users was introduced in version 3.15. All users need to meet the following requirements before any of them are created:

• All required fields are filled in
• The password is at least 8 characters long and difficult to guess
• The phone number is valid when token_login is enabled

Users are created in parallel and the creation is not aborted even if one of the users fails to be created.

Passing a single user in the request’s body will return a single object whereas passing an array of users will return an array of objects as shown in the examples below.

Permissions

Creating users from a CSV file behaves the same as passing a JSON array of users into the POST /api/v1/users where a row represents a user object and a column represents a user object property.
Columns with a :excluded suffix will be ignored, this allows providing a more user-friendly experience with autocompletion on fields or dealing with names instead of long, unreadable ids.

In order to facilitate this process, we have made available a spreadsheet compatible with the default configuration of the CHT. Click here to make a copy of the spreadsheet in Google Sheets.
A guide on how to import users with this spreadsheet from within the Admin Console is available in case you don’t want to interact with this API yourself.

Logging

A log entry is created with each bulk import that contains the import status for each user and the import progress status that gets updated throughout the import and finalized upon completion.
These entries are saved in the medic-logs database and you can access them by querying documents with a key that starts with bulk-user-upload-.

Headers

Permissions

can_create_users

Example

Create two new users that can authenticate with a username and a password that can submit reports and view or modify records associated to their place. Along with a new user, a new contact and new place are created as well. The new place will be a child of place.parent (see the UUID fe4da0f9-7d65-4834-bb42-88a5239bbd3b below) and must already exist or else the new place will be an orphan record in the hierarchy and not show up in the GUI.

POST /api/v1/users/{{username}}

Allows you to change property values on a user account. Properties listed above are supported except for contact.parent. Creating or modifying people through the user is not supported, see People section.

Permissions

can_update_users, can_update_places, can_update_people

Updating yourself

You do not need any of the above permissions if the user you are modifying is yourself. However, you are not allowed to modify your type, roles, contact or place.

Further more, if you’re updating your password you must be authenticating via Basic Auth (either the header or in the URL). This is to ensure the password is known at time of request, and no one is hijacking a cookie.

URL Parameters

{
  "password": "secret",
  "place": "eeb17d6d-5dde-c2c0-62c4a1a0ca17e342"

DELETE /api/v1/users/{{username}}

Delete a user. Does not affect a person or place associated to a user.

Permissions

can_delete_users

URL Parameters

Examples

DELETE /api/v1/users/mary

HTTP/1.1 200 OK

GET /api/v1/users-info

Returns the total number of documents an offline user would replicate (total_docs), the number of docs excluding tasks the user would replicate (warn_docs), along with a warn flag if this number exceeds the recommended limit (now set at 10 000).

When the authenticated requester has an offline role, it returns the requester doc count.

Example

GET /api/v1/users-info -H 'Cookie: AuthSession=OFFLINE_USER_SESSION;'

HTTP/1.1 200 OK
Content-Type: application/json

{
  "total_docs": 5678,
  "warn_docs": 4852,
  "warn": false,
  "limit: 10000
}

When the requester has an online role, the following query parameters are accepted:

Query Parameters

When requested as an online user, the number of tasks are never counted and never returned, so warn_docs is always equal to total_docs.

Example

GET /api/v1/users-info?facility_id={{facility_uuid}}&role={{role}}&contact_id={{contact_uuid}} -H 'Cookie: AuthSession=OFFLINE_USER_SESSION;'

HTTP/1.1 200 OK
Content-Type: application/json

{
  "total_docs": 10265,
  "warn_docs": 10265,
  "warn": true,
  "limit: 10000
}

In case any of the required query parameters are omitted or the requested role is not configured as an offline role, the request will result in an error:

GET /api/v1/users-info?role={{online_role}} -H 'Cookie: AuthSession=OFFLINE_USER_SESSION;'

HTTP/1.1 400 Bad Request
Content-Type: application/json

{
  "code": 400,
  "error": "Missing required query params: role and/or facility_id"
}

Bulk Operations

POST /api/v1/bulk-delete

Bulk delete endpoint for deleting large numbers of documents. Docs will be batched into groups of 100 and will be sent sequentially to couch (new batch sent after the previous one has returned). The response will be chunked JSON (one batch at a time), so if you wish to get an indication of progress you will need to parse incomplete JSON (with a library such as partial-json-parser.

Permissions

Only available to online users.

Parameters

An array of objects each with an _id property is required (rather than an array of strings representing ids) to ensure forwards compatibility if we choose to require that any additional document information (such as _rev) also be passed in to this endpoint.

Errors

If an error is encountered part-way through the response (eg on the third batch), it’s impossible to send new headers to indicate a 5xx error, so the connection will simply be terminated (as recommended here https://github.com/expressjs/express/issues/2700).

Examples

POST /api/v1/bulk-delete
Content-Type: application/json

{
  "docs": [
    { "_id": "id1" },
    { "_id": "id2" },
    ...
    { "_id": "id150" }
  ]
}

Monitoring

See the Monitoring and alerting on the CHT page for how to use this API in production.

GET /api/v1/monitoring

Deprecated in 3.12.x in favor of /api/v2/monitoring Used to retrieve a range of metrics about the instance. While the output is human-readable this is intended for automated monitoring allowing for tracking trends over time and alerting about potential issues.

Permissions

No permissions required.

Examples

JSON format

curl http://localhost:5988/api/v1/monitoring

{"version":{"app":"3.9.0","node":"v10.16.0","couchdb":"2.3.1"},"couchdb":{"medic":{"name":"medic","update_sequence":5733,"doc_count":278,"doc_del_count":32,"fragmentation":1.0283517758420173}...

Response content

Errors

• A metric of "" (for string values) or -1 (for numeric values) indicates an error occurred while querying the metric - check the API logs for details.
• If no response or an error response is received the instance is unreachable. Thus, this API can be used as an uptime monitoring endpoint.

GET /api/v2/monitoring

Available as of 3.12.x. Used to retrieve a range of metrics about the instance. While the output is human-readable this is intended for automated monitoring allowing for tracking trends over time and alerting about potential issues.

Permissions

No permissions required.

Examples

JSON format

curl http://localhost:5988/api/v2/monitoring

{"version":{"app":"3.12.0","node":"v10.16.0","couchdb":"2.3.1"},"couchdb":{"medic":{"name":"medic","update_sequence":5733,"doc_count":278,"doc_del_count":32,"fragmentation":1.0283517758420173}...

Response content

Errors

• A metric of "" (for string values) or -1 (for numeric values) indicates an error occurred while querying the metric - check the API logs for details.
• If no response or an error response is received the instance is unreachable. Thus, this API can be used as an uptime monitoring endpoint.

Upgrades

All of these endpoints require the can_configure permission.

All of these endpoints are asynchronous. Progress can be followed by watching the horti-upgrade document and looking at the log property.

POST /api/v1/upgrade

Performs a complete upgrade to the provided version. This is equivalent of calling /api/v1/upgrade/stage and then /api/v1/upgrade/complete once staging has finished.

Example

POST /api/v1/upgrade
{
  "build": {
    "namespace": "medic",
    "application": "medic",
    "version": "3.0.0-beta.1"
  }
}

For potential forwards compatibility, you must pass the namespace and application as medic.

The version should correspond to a release, pre-release or branch that has been pushed to our builds server, which is currently hard-coded to https://staging.dev.medicmobile.org/builds. This happens automatically upon a successful Continuous Integration run.

Calling this endpoint will eventually cause api and sentinel to restart.

It is expected that the caller ensures forwards or backwards compatibility is maintained between deployed versions. This endpoint does not stop you from “upgrading” to an earlier version, or a branch that is incompatible with your current state.

POST /api/v1/upgrade/stage

Stages an upgrade to the provided version. Does as much of the upgrade as possible without actually swapping versions over and restarting.

Parameters are the same as /api/v1/upgrade.

You know that an upgrade has been staged when the horti-upgrade document in CouchDB has "action": "stage" and "staging_complete": true.

POST /api/v1/upgrade/complete

Completes a staged upgrade. Throws a 404 if there is no upgrade in the staged position.

Hydrate

Accepts a JSON array of document uuids and returns fully hydrated documents, in the same order in which they were requested. When documents are not found, an entry with the missing uuid and an error is added instead. Supports both GET and POST. Only allowed for users with “online” roles.

GET /api/v1/hydrate

Query parameters

Example

GET /api/v1/hydrate?doc_ids=["id1","missingId","id3"]

HTTP/1.1 200 OK
Content-Type: application/json

[
  { "id": "id1", "doc": { <...the hydrated document...> } },
  { "id": "missingId1", "error": "not_found" },
  { "id": "id3", "doc": { <...the hydrated document...> } },
]

POST /api/v1/hydrate

Parameters

Example

POST /api/v1/hydrate
Content-Type: application/json

{
  "doc_ids": ["id1","missingId","id3"]
}

HTTP/1.1 200 OK
Content-Type: application/json

[
  { "id": "id1", "doc": { <...the hydrated document...> } },
  { "id": "missingId", "error": "not_found" },
  { "id": "id3", "doc": { <...the hydrated document...> } },
]

Contacts by phone

Added in 3.10.0 Accepts a phone number parameter and returns fully hydrated contacts that match the requested phone number. If multiple contacts are found, all are returned. When no matches are found, a 404 error is returned. Supports both GET and POST. Only allowed for users with “online” roles.

GET /api/v1/contacts-by-phone

Query parameters

Example

GET /api/v1/contacts-by-phone?phone="%2B40-(744)-999-999"

HTTP/1.1 200 OK
Content-Type: application/json

{
  "ok": true,
  "docs": {
    { <... first hydrated matching contact found ...> },
    { <... second hydrated matching contact found ...> },
    ...
  }
}

POST /api/v1/contacts-by-phone

Parameters

Example

POST /api/v1/contacts-by-phone
Content-Type: application/json

{
  "phone": "+40 (21) 222-3333"
}

HTTP/1.1 200 OK
Content-Type: application/json

{
  "ok": true,
  "docs": {
    { <... first hydrated matching contact found ...> },
    { <... second hydrated matching contact found ...> },
    ...
  }
}

Replication Limit

Added in 3.11.0 Returns the quantity of documents that were replicated by each user. Accepts filtering by user name, when not provided, it returns all users. Supports GET. Only allowed for users with “_admin” role.

GET /api/v1/users-doc-count

Query parameters

Example

GET /api/v1/users-doc-count?user=mary"

HTTP/1.1 200 OK
Content-Type: application/json

{
    "limit": 10000,
    "users": {
        "_id": "replication-count-mary",
        "_rev": "5-cd3252e852ae075da216c3c3fe461291",
        "user": "mary",
        "date": 1595328973273,
        "count": 58
    }
}

Credentials

Securely store credentials for authentication with third party systems such as SMS aggregators and HMIS. Certain CHT services rely on these credentials when enabled.

PUT /api/v1/credentials

Added in 4.0.0

Provide the credential key as a URL parameter and the password in the request body, for example, to set a credential with key “mykey” and password “my pass” use the following command.

curl -X PUT -H "Content-Type: text/plain" https://<user>:<pass>@<domain>/api/v1/credentials/mykey -d 'my pass'

3.x API

For 3.x deployments credentials are stored in CouchDB configuration in a custom medic-credentials section.

To add the credential to the admin config you need to PUT the value using curl, for example, to set a credential with key “mykey” and password “my pass” use the following command.

curl -X PUT https://<user>:<pass>@<domain>/_node/_local/_config/medic-credentials/mykey -d '"my pass"'

You can also add it via Fauxton:

• Navigate to the Config screen at https://<domain>/_utils/#/_config
• Click Add Option
• The Section should be medic-credentials, the Name should be (in this example) mykey and the value should be the password
• Click Create
• You should then be able to see your credential in the list of configuration shown
