KoBo API examples, using new KPI endpoints


This is copied from some private correspondence I had a while ago. Perhaps it’s useful to someone in this format, until more official documentation is developed for the new API :slight_smile: In writing “new,” I’m contrasting KPI to the old KoBoCAT (/api/v1) API.

KoBo API Examples

I’ve used curl to demonstrate these API calls. You’ll notice that all my curl commands begin with curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' and end by being piped to python -m json.tool. The python call simply formats the JSON response to make it easier to read. The --silent flag to curl is not required, but it makes the output cleaner for the purposes of this demonstration. Basic authentication with --user username:password as I’ve done is fine, but you may also authenticate using a token retrieved at https://kobo.humanitarianresponse.info/token/ by sending the header Authorization: Token [your-token]. Including the header Accept: application/json for all requests is highly recommended to avoid having the API return “browseable” HTML that is not easily parsed.

Importing a form

Uploading the XLSForm

POST a new import as a multipart form. The necessary parameters are library=false and file, which cotains the XLSForm:

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X POST https://kobo.humanitarianresponse.info/imports/ --form library=false --form file=@kobo_1701_NW.xlsx | python -m json.tool
    "status": "processing",
    "uid": "iGYukk6NVEA64zwMsPtgRD",
    "url": "https://kobo.humanitarianresponse.info/imports/iGYukk6NVEA64zwMsPtgRD/"

Getting the resulting asset UID

The asset UID is given by messages.created[0].uid in the JSON response when GETting an import. Multiple GETs may be required until the server indicates "status": "complete" in the response:

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' https://kobo.humanitarianresponse.info/imports/iGYukk6NVEA64zwMsPtgRD/ | python -m json.tool

Working with existing forms

Deploying an asset

Construct a URL using the asset UID: https://kobo.humanitarianresponse.info/assets/[your-asset-UID]/deployment/; then, POST with the form parameter active=true.

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X POST https://kobo.humanitarianresponse.info/assets/apLBsTJ4JAReiAWQQQBKNZ/deployment/ --form active=true | python -m json.tool
    "active": true,
    "backend": "kobocat",
    "identifier": "https://kc.humanitarianresponse.info/jnm_api/forms/apLBsTJ4JAReiAWQQQBKNZ",
    "version_id": "vh9JnfrRNwVFjJZnSwRYqd"

Rename a form

Send a PATCH to the asest URL, i.e. https://kobo.humanitarianresponse.info/assets/[your-asset-UID/, with the form parameter name=[Your New Name]. If your form is large, the response will be large as well! I have omitted the output below for that reason.

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X PATCH https://kobo.humanitarianresponse.info/assets/apLBsTJ4JAReiAWQQQBKNZ/ --form name='My New Name' | python -m json.tool

:warning: If the form was already deployed, you must redeploy the form for the name change to appear in data collection clients.

Redeploy a form

First, retrieve the UID of the latest version of the asset by making a GET request to the asset URL. Again, if your form is large, the response will be large as well. Here, I use a simple grep to restrict the output to the property I want: version_id.

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' https://kobo.humanitarianresponse.info/assets/apLBsTJ4JAReiAWQQQBKNZ/ | python -m json.tool | grep version_id
    "deployed_version_id": "vh9JnfrRNwVFjJZnSwRYqd",
    "version_id": "ve338oJQooAbkyar7qjukR",

Note that deployed_version_id is not equal to version_id, indicating that the form has been changed since the last deployment.

Now, send a PATCH to https://kobo.humanitarianresponse.info/assets/[your-asset-UID]/deployment/ with the form parameter version_id set to the UID of the latest version of the form obtained above.

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X PATCH https://kobo.humanitarianresponse.info/assets/apLBsTJ4JAReiAWQQQBKNZ/deployment/ --form version_id=ve338oJQooAbkyar7qjukR | python -m json.tool
    "active": true,
    "backend": "kobocat",
    "identifier": "https://kc.humanitarianresponse.info/jnm_api/forms/apLBsTJ4JAReiAWQQQBKNZ",
    "version_id": "ve338oJQooAbkyar7qjukR"

Clone a form

POST to https://kobo.humanitarianresponse.info/assets/ with the form parameter clone_from set to the UID of the asset that should be cloned. You may also include a name parameter that sets the name of the new asset. Again, if you form is large, the response will be large. Just to make this demonstration easier to read, I pipe the output to tail:

jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X POST https://kobo.humanitarianresponse.info/assets/ --form clone_from=apLBsTJ4JAReiAWQQQBKNZ --form name='My Cloned Form' | python -m json.tool | tail
        "row_count": 1269
    "tag_string": "",
    "uid": "a9Cufbcm2GsqD5oh7u5wXd",
    "url": "https://kobo.humanitarianresponse.info/assets/a9Cufbcm2GsqD5oh7u5wXd/",
    "version_count": 1,
    "version_id": "vq7Xi8wmQYuB4BT3uBdxE3",
    "xform_link": "https://kobo.humanitarianresponse.info/assets/a9Cufbcm2GsqD5oh7u5wXd/xform/",
    "xls_link": "https://kobo.humanitarianresponse.info/assets/a9Cufbcm2GsqD5oh7u5wXd/xls/"

The new asset's UID is given by the uid property in the response.
:warning: The new asset will not be deployed automatically, even if the source asset was deployed.

Share a form

Sharing requires a POST to https://kobo.humanitarianresponse.info/permissions/ with three form parameters:

  • content_object: the URL, relative or absolute, of the asset to be shared, e.g. ``/assets/aSAKqcFRv9nYWqiKGvZC7w/`;
  • permission: a string indicating the permission to grant, e.g. change_asset. This can be any assignable permission for an asset;
  • user: the URL, relative or absolute, identifying the user who will receive the new permission, e.g. /users/jnm/. The last component of the URL is the username.
jnm@world:/tmp/api_demo$ curl --silent --user jnm_api:some-secret-phrase --header 'Accept: application/json' -X POST https://kobo.humanitarianresponse.info/permissions/ --form content_object=/assets/apLBsTJ4JAReiAWQQQBKNZ/ --form permission=change_asset --form user=/users/jnm/ | python -m json.tool
    "content_object": "https://kobo.humanitarianresponse.info/assets/apLBsTJ4JAReiAWQQQBKNZ/",
    "deny": false,
    "inherited": false,
    "kind": "objectpermission",
    "permission": "change_asset",
    "uid": "pnjnsQXCYEYVSTSXvKAYum",
    "url": "https://kobo.humanitarianresponse.info/permissions/pnjnsQXCYEYVSTSXvKAYum/",
    "user": "https://kobo.humanitarianresponse.info/users/jnm/"

Is there an API to add validate permission for a user to a form

Is there an API endpoint to create users in kobo?


please… we need a complete documentation for the new API
