# API keys

### How do I get an API key?

Contact us at [go.gov.sg/contact-paysg](https://go.gov.sg/contact-paysg) with a valid gov.sg email for an API key to be provisioned. Please ensure that the email address has been used to log in to [staging.pay.gov.sg](https://staging.pay.gov.sg) and [pay.gov.sg](https://pay.gov.sg) before. Note that the API key holder must be added as a Billing collaborator on the payment service.

### Why doesn't my API key work?

Ensure that the email address the API key was issued to is added as a Billing collaborator to the payment service.

### Do I need a new API key for each payment service?

No, API keys are associated with email addresses, not payment services. As long as the API key holder is added as a Billing collaborator on the relevant payment service, the API key can be used to create payments via API.

### Does the API key expire?

No, our API keys do not currently expire.

### What email address should I use for the API key?

We typically suggest teams to use a group email address (e.g. <agency-finance-team@agency.gov.sg>).

### What happens to the API key if the API key holder leaves the organisation?

The API key will still remain valid. However, we strongly suggest the team either use a group email for the API key, or ensure that a new API key is issued to someone within the organisation.
