How should I authenticate requests?

Important Note for Merchant and Payment Gateway API requests

Merchant and payment gateway API requests are authenticated using HTTP Basic Authentication. When you submit a request, you must always base64-encode the public or secret key plus a trailing colon, using tools such as base64 (OS X/Linux) or certutil (Windows).

For example, if your public key is: m_cSiyNUh9RBWHfdbFRFGrkA, you’ll base64-encode m_cSiyNUh9RBWHfdbFRFGrkA:. The result is bV9jU2l5TlVoOVJCV0hmZGJGUkZHcmtCOg==, which you’ll use in your request header.

How can I test payments?

You can use test card numbers and test bank accounts to make test payments.

Are there examples for requests?

Every operation you can perform using the API has a corresponding example request and response in the API Reference. The examples are in cURL and have the following structure:

curl -X <method> -H <content_type> <authentication> <endpoint_url> -d `{<request_body>}`

Here’s a description of each part of this request:

ComponentDescription
<method>The type of operation that the request will perform, such as POST to create an object.
<content_type>The type of data that will be passed in the request body.
<authentication>The key or token used to authenticate the request.
<endpoint_url>The API endpoint where the request is sent.
<request_body>The request body. It must be surrounded by single quotes.

Here’s an example request using each of these components:

curl -X POST -H "Content-Type:application/json" --user AbCdEfG= https://api.chargeio.com/v1/charges -d '
  {
      "amount": "100",
      "account_id": "1A2B3C",
      "method": {
          "type": "card",
          "number": "4242424242424242",
          "exp_month": 10,
          "exp_year": 2022,
          "cvv": "123",
          "name": "Some Customer"
      }
  }'
