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

POST /api/v2/records

Create a new record based on a JSON form that has been configured.

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.

Examples

Creating new record using message field.

POST /api/v1/records
Content-Type: application/x-www-form-urlencoded

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/{{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

Examples

POST /api/v1/users/mary

URL Parameters

Examples

DELETE /api/v1/users/mary

HTTP/1.1 200 OK

GET /api/v1/users-info

Returns the number of documents an offline user would replicate, 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": false,
  "limit: 10000
}

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

Query Parameters

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": 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" }
  ]
}

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

[
  [
    { "ok": true, "id": "id1", "rev": "1-rev1" },
    { "ok": true, "id": "id2", "rev": "1-rev2" },
    ...
    { "ok": true, "id": "id100", "rev": "1-rev100" }
  ],
  [
    { "ok": true, "id": "id101", "rev": "1-rev101" },
    { "ok": true, "id": "id102", "rev": "1-rev102" },
    ...
    { "ok": true, "id": "id150", "rev": "1-rev150" }
  ]
]

Monitoring

GET /api/v1/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 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 travis 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
