2. Select an email address for the API key to be issued to. We recommend using a group email address (e.g. <agency_finance_team@agency.gov.sg>) for transferability.
3. (Optional) For webhook registration, share the webhook URL with the PaySG team.

**You will need to share the following information with PaySG (<team@pay.gov.sg>):**

* Payment service ID
* Email address for API key

  1. Payment service ID
  2. Agency UEN
  3. DBS account number
  4. DBS API key (provided by DBS)
  5. DBS organisation ID (provided by DBS)
