Introduction<\/h3>\n\n\n\n

In this post I followed the powens API documentation to retrieve my mobile phone provider bills automatically.<\/p>\n\n\n\n

Powens is a company known for OpenBanking solutions, mainly the aggregation of user banking transactions and financial assets, but it also has a product called “Trust” that allows you to download periodically documents from your Banks, Government Authorities, Utility companies etc.<\/p>\n\n\n\n

Powens does all this leveraging the power of the opensource framework https:\/\/woob.tech\/<\/a>.<\/p>\n\n\n\n

You can find the integrations (aka connectors) supported by Powens in the following link https:\/\/institutions.powens.com\/<\/a>. Perhaps the most interesting are listed in the “Bank” and “Wealth” products. Below are some of the connectors for “Trust”.<\/p>\n\n\n\n

Integrating connectors from “Bank”, “Wealth” and “Trust” follows the same logic, in this post I would use the integration to Free Mobile.<\/p>\n\n\n\n

Registering an Application in Powens<\/h3>\n\n\n\n

The first step is to register myself in https:\/\/console.powens.com, actvate the Free Mobile “connector” and follow the workflow to create an “application”.<\/p>\n\n\n\n

Screenshot below shows the activation of the Free Mobile connectors:<\/p>\n\n\n\n

This screnshot shows my client application<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Once the application is created, Powens provides you with a client_id and a client_secret.<\/p>\n\n\n\n

Remember, Powens is in the B2B business. When you log in, you are a “company” integrating Powens: You are configuring Powens so that your clients (or you personally) can use Powens’ services.<\/p>\n\n\n\n

The “user” in this sense is the person who’s data is going to be fetched by Powens. In this case, it’s me, since I want to download my mobile phone bills.<\/p>\n\n\n\n

Creating a “User” and Getting an Auth Token<\/h3>\n\n\n\n

With the following request, we can create a user. Bear in mind that cam.biapi.pro is the name of the domain that I choose when setting up my account in powens. “cam” are my initials, and biapi.pro is powens’ domain.<\/p>\n\n\n\n
