Adding Merchant Credentials

To establish an API connection with Checkout for a merchant who already has a relationship with them, you will need to provide the following credentials:

• Checkout Processing Channel ID
• Checkout Public Key
• Checkout Secret Key

You may upload this via the Preczn Dashboard, merchant import or by updating the merchant connection via Update Connection Details endpoint. The values needed in the request would map as follows:

PATCH /v1/merchants/{merchantId}/connections/Checkout 

{
    "mid": "{checkout-processing-channel-ID}",  
    "key": "{checkout-public-key}", 
    "secret": "{checkout-secret-key}" 
}
