Checkout.com provides a collection of APIs that enable you to integrate with our various products and services. Our APIs accept and return JSON in the HTTP body, and return standard HTTP response codes. You can consume the APIs directly using any HTTP or REST library. Sign up for a test account to gain access to the sandbox environment, where you can test API calls without affecting live data. For more information, see:
The base URLs you must use for your API calls to the sandbox and production environments are unique to you.
https://{prefix}.api.sandbox.checkout.com/{path}https://{prefix}.api.checkout.com/{path}
The {prefix} value in each base URL is a string containing the first eight characters of each of your environments' unique client_id, excluding the cli_ prefix.
To find your unique base URL:Sign in to the Dashboard environment you want to retrieve the base URL for:
Go to Developers > Overview.
Your unique base URL is displayed on the Developer overview page. For example, https://vkuhvk4v.api.checkout.com.
Alternatively, go to Settings > Account details.
Your unique base URL is displayed under Connection settings.
If you are unsure of your client ID or base URL for either environment, contact your account manager or request support.
For more information, see API endpoints.
When you sign up for an account, you can authenticate with either Access keys (OAuth 2.0), or Secret API keys. Unless explicitly stated, all endpoints require authentication using either your Access or Secret API Keys. Public keys should only be used in JavaScript or native applications.
Public keys are for client-side authentication and supported only in JavaScript or native applications.
Sandbox – pk_sbox_xxxxxxxxxxxxxxxxxxxxxxxxxx
Production – pk_xxxxxxxxxxxxxxxxxxxxxxxxxx
When specifying your public key, use the format Bearer {{PublicApiKey}}.
You can pass your secret API key in the Authorization header of your requests for supported endpoints.
Sandbox – sk_sbox_xxxxxxxxxxxxxxxxxxxxxxxxxx
Production – sk_xxxxxxxxxxxxxxxxxxxxxxxxxx
When specifying your secret key, use the format Bearer {{SecretApiKey}}.
curl --location --request POST 'https://{prefix}.api.checkout.com/{{path}}' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer {{SecretApiKey}}' \
--data-raw '{
"amount": 10000,
"currency": "USD",
"reference": "Visa-USD-Test",
...
}'
Your OAuth credentials include an access key ID and an access key secret. They correspond to an OAuth 2.0 client ID and a client secret respectively.
To exchange these credentials for an access token, call the Request an access token endpoint. Authenticate using basic authentication, with your access key ID as the username and your access key secret as the password.
| Environment | Authorization server |
|---|---|
| Sandbox | https://{prefix}.access.sandbox.checkout.com/connect/token |
| Production | https://{prefix}.access.checkout.com/connect/token |
curl --location 'https://{prefix}.access.checkout.com/connect/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'client_id=ack_...' \
--data-urlencode 'client_secret=...'
The token server returns a Bearer access_token in JSON Web Token (JWT) format. Use this token in the Authorization header of your API requests.
curl --location --request POST 'https://{prefix}.api.checkout.com/{{path}}' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'Authorization: Bearer {{AccessToken}}' \
--data-raw '{
"amount": 10000,
"currency": "USD",
"reference": "Visa-USD-Test",
...
}'
The expires_in field in the response indicates the validity period of your access token in seconds. When your token expires, you must request a new one.
Depending on the Environment against which you're making your requests against you'll need to request the token from a different Authorization Server.
| Environment | Authorization Server |
|---|---|
| Sandbox | https://{prefix}.access.sandbox.checkout.com/connect/token |
| Production | https://{prefix}.access.checkout.com/connect/token |
Your base URL {prefix} is unique. To learn how to retrieve your unique base URLs for the sandbox and production environments, see API endpoints.
