If you’re stumped, you can find help in the following places:

  • API Developer Forum: This is a good place to ask general questions about the API, report unexpected behavior, or track issues.
  • FAQ: We post the most popular questions from the forum here.
  • Customer Service: If there are problems with orders that are impacting end-users (on production server), our customer service team can help with orders or payment issues. They will not be able to help with technical questions about the API.

FAQ – Frequently Asked Questions

Why am I getting an HTTP 401 / Incorrect API Key / “acct_invalid_xauth” response?

All API requests are authenticated and tracked by our system. You will need to either pass in your client_id (for unauthenticated resources) or an oauth access token (for POST requests and customer resources).

Please check out the authentication overview and Access Token overview.

How do I sign up for an account?

You will receive an API key upon signing up.

Do you have a list of sample (geo) search address that contain plenty of merchants?

  • Park Ave S, 10003
  • 199 Water Street, 10038
  • 1001 6th Avenue, 10018

What geolocation address do you support?

Any fully qualified address queries should work (street address, city, zipcode and state). However, you could also pass in:

Elements Example
Fully Qualified Address 1001 6th Avenue, New York, NY 10018
Street Address + Zipcode 1001 6th Avenue, 10018
Latitude + Longitude 40.751992, -73.986582

What is the Complete List of Credit Card Types?

Our API will return one of the following 5 credit ctypes in the “card.type” field of the customer payment endpoint:

  • Visa
  • MasterCard
  • Discover
  • American Express
  • Diners Club

Is there a built-in way to redeem point rewards via the API?

Sorry to say but we don’t currently support a redirect from our rewards page. I don’t believe we are going to support either unless there is large demand for that ability. There is a endpoint /api/prizes that we do not document. If you like, you can inspect the request on https://www.delivery.com/delivery-points and see how we handle it to get around the need to redirect back to your app or site.
