DevApp creation

 In general, think of Developer application (a.k.a., DevApp) as a container that stores your API access configuration:

  • Credentials
  • Selected ConnectPay API products
  • List of Callback URLs
  • BrandId
  • etc

List DevApps

Create New DevApp

While in above mentioned My Apps page press Register New App button.

  • Enter Name.
  • From API Available list select API products that you want to use.

Note: You will be able to modify API list at any time.

  • If any of selected API products would require Callbacks or Browser redirects, you will have to enter these URLs in Callback URL field. You can enter as many comma separated URLs as you need.
  • Each hostname of callback URL in API requests will be validated against this list. 
  • Always specify protocol along with hostname which consists of subdomain and domain. Use only https protocol, http is disabled.
  • Example of callback URL list:,
  • If you are using Merchant API, enter assigned Brand ID into MERCHANT API – BRAND ID field.
