Proposable's API is designed around REST with a simple resource-specific URL structure. All responses are JSON-encoded.

Check out the full API Reference here.

Base URL

The API can be accessed via:


Requests can be authenticated using your personal API access token, or through a custom OAuth 2 client access token.

Access tokens can be sent as a Query Parameter, for example

Or as an Authorization header Bearer token, for example

Authorization: Bearer your-access-token

OAuth 2 Clients and Third-Party Applications

Create an OAuth 2 Client for your application to access accounts outside of your organization.

The system will ask for the Name of your application and the Redirect URI.

OAuth 2 Authorization and Token Generation

After generating an Oauth 2 Client, you will receive a Client ID and a Secret Key

To gain access to an account outside of your organization using your OAuth 2 Client

1. Send the user to the authorization endpoint, for example:

Required Arguments

  • client_id

  • response_type

    • The value should be code

  • redirect_uri

2. Trade the provided code for a valid Access Token

After the user authenticates and authorizes your application, the system will redirect the user back to your application via the redirect_uri and return the code query parameter.

To retrieve the user's access token, make a POST request to the /oauth/token endpoint with the following parameters:

  1. client_id

  2. client_secret

  3. code (provided on redirect)

  4. grant_type

    1. The value should be authorization_code

  5. redirect_uri

Here is a quick example of this request using CURL

curl -X POST \
-H "Content-Type: application/x-www-form-urlencoded" \
-d client_id=your-client-id \
-d client_secret=your-client-secret \
-d code=the-code-provided-on-redirect \
-d grant_type=authorization_code \
-d redirect_uri=

Next Steps

Now that you have access token(s) you can begin making requests to the API. The Proposable API allows you to manage proposals, templates, contacts, and more.
