Adding app authentications

Adding an authentication to your own app

Confirm your app's authentication_fields

When you created your app in the Zapier Developer Platform, a required step was to define the fields required for authentication. Depending on your authentication scheme the authentication_fields below will differ.

Form & send your request

Leveraging the Create authentication endpoint, supply your app’s required authentication_fields in the request.

    // POST /authentications
    "data": {
        "app": "{MY_APP_ID}",
        "title": "{AUTHENTICATION_NAME}",
        "authentication_fields": {
            "username": "{MY_USERS_USERNAME}",
            "password": "{MY_USERS_PASSWORD}"
        }
    }

    // POST /authentications
    "data": {
        "app": "{MY_APP_ID}",
        "title": "{AUTHENTICATION_NAME}",
        "authentication_fields": {
            "api_key": "{MY_USERS_API_KEY}",
        }
    }

Be sure to supply whatever authentication_fields are required by your apps’ authentication scheme.

Pick an authentication name that’ll be recognizable to a user should they find it outside of this flow, such as “Carter’s LinkedIn Authentication”, or “Micah’s Slack Authentication”

Leverage the new authentication in subsequent workflow steps

A successful response from this request will include an id, which can be used in subsequent steps.
