The Activation API requires an access token for you and your customers.
Use the access_token from the response to authorize Activation API calls.
Authorization: Bearer ${access_token}
About access token expiration and rate limits
Access tokens expire quickly. See the
expires_invalue for the time limit. The example above shows 10 minutes (600 seconds). To insure that calls to Activation API endpoints are successful, set up an automated way to fetch new access tokens.The token endpoint rate limit is 4 requests per second. We recommend that you cache the
access_tokenrather than fetch a new token for every API request.
