Introduction

Welcome to the Merit API! You can use our API to access Merit Giftcard platform.

This API has been created for partners to connect to the Gift Card Platform to create gift cards and send it to customers

• Current version of the API is V3 and the endpoints will be prefixed by v3/.

Authentication

Merit uses token based authentication. API keys to allow access to the API.

The client needs to send HTTP requests with the Authorization header that contains the word ‘Bearer’ followed by a space and the Key Secret.

Merit expects for the API key to be included in all API requests to the server in a header that looks like the following:

Authorization: Bearer secret_token

To authorize, use this code:

# With shell, you can just pass the correct header with each request
curl "api_endpoint_here"  \

-H  "Authorization: Bearer secret_key"

Make sure to replace secret_key with your API key.

Merit uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted). Codes in the 5xx range indicate an error with Merit's servers (these are rare).

Idempotency

Merit support idempotency to provides protection against accidental duplicate calls causing unintended consequences.

The client needs to send HTTP requests with the idempotency-key header that contains unique identifier string with a maximum of 20 - 64 characters.

If the idempotency-key is not provided, the request will be processed without considering idempotency, potentially leading to duplicate request processing.

Idempotency is applicable only to POST and DELETE calls; idempotency keys sent in GET calls will be ignored.

idempotency key header that looks like the following:

idempotency-key: XXXX-XXXXX-XXXXXX-XXXX

curl "api_endpoint_here"  \

-H  "idempotency-key: XXXX-XXXXX-XXXXXX-XXXX"

Throttle rate

Merit API will throttle/decline incoming requests to prevent misuse of the system. The request rate cannot exceed more than specified below.

When requests from your code exceed a throttle rate, your request fails and a ThrottlingException is returned with a HTTP status code 429 (Too Many Request)

Response will contain following headers.

• RateLimit-Limit: The maximum number of requests you're permitted to make per hour.

• RateLimit-Reset: the time at which the current rate limit window resets in UTC epoch seconds
