How do I register on the Developer Portal to access the sandbox APIs?

You need to have ordered the product here in order to be invited. You will not be able to create an app and access the REST API to make test calls to them, unless you have been invited.

  1. Firstly, you will be contacted by MobilePay Business who will handle the product onboarding.
  2. Secondly, the DeveloperSupport team will handle your technical onboarding. 
  3. After having received the confirmation email and completed configuring your account, you will be able to login and start using our MobilePay test environment.

Once the above is handled, then you will receive an invite to MobilePay Sandbox Developer Portal, where you must create an user. The Developer Portal is primarily used by the technical contact. If there are more developers, who should be invited to the Developer Portal, please let us know and forward us their e-mail address, and then we will invite them.

The first steps

1. Log-in: 

In sandbox the URL is and for production the URL is

Credentials are created using the mail invites received from the MobilePay Developer Support.

2. Create an app:

From the developer portal, click on your e-mail in the top and choose ”My Apps” at the top of the page. Click the create new app button.  

NOTE: You can create more than 1 app, but it is up to you and your implementation. How you handle the data internally in your organisation is up to you, and not MobilePay. If you decide to create more apps, then you also need to manage the data. We recommend that you keep it simple and stick to one app.

We have one example of a merchant that has 3 apps, but as the merchant is a Publishing company, they are providing 3 different magazines. 3 different magazines means 3 different services that the customer can buy. Therefore, they chose to have 3 apps. Otherwise, all other merchants have 1 app. 

Once you have provided an application name, description, etc. the system automatically generates a set of client-secret and clientSecret for your app. You will be shown your application client_id and client_secret

Make a note of your client_secret because it is only displayed once. You must supply the credentials when you call an API that requires you to identify your app by using a Client ID and Client secret.  

For example, If you have two apps, then you need to manage the Client-secret and ClientSecret for 2 different apps. 

3. Subscribe to API's

Now that you’ve registered your app, you need to subscribe to Invoice and/or Subscriptions API's, depending on your need.
