Take your integration live

[Step 6 of 6] In this step, you will update your integration to use production values and review a pre-launch checklist. At the end of this step, you will be able to process live transactions.

1. Update publicKeyId

In the button integration code, replace publicKeyId with your Live API public Key ID. Repeat the get your public key ID instructions to generate the Live public Key ID. Be sure to select the "Production" option from the "Marketplace switcher" drop-down in step 2.

Common integration issues

Some Amazon Pay transactions are processed asynchronously. This means that Amazon Pay will return a pending response and the object will be in an Pending state until processing is complete. If applicable, make sure that you’re handling asynchronous processing.
Amazon Pay returns a string string for buyer name. Make sure you’re parsing the buyer name correctly. Note that some buyers may only provide a single name, e.g. “Jane”.

1. Update the button-rendering code

In the button integration code, remove the sandbox parameter. You must also generate a new signature if payloadJSON changes.

US	https://pay-api.amazon.com/sandbox/:version	https://pay-api.amazon.com/live/:version
EU/UK	https://pay-api.amazon.eu/sandbox/:version	https://pay-api.amazon.eu/live/:version
