The following tips may help you to avoid frequently occurring problems or questions:

1.) API key (secret) of the Marketplace API user vs. provider secret : Please do not confuse the two different secrets that are used. The secret, also known as the API key, of your API user is explained here . The provider secret is required for the signature and is explained in more detail here .

2.) We have created your own provider customer so that you can test your service yourself. All purchases that customers have made with your service are also listed in this provider customer. A Marketplace account has already been created and your service can be activated and used.

3.) Do not create your own API user in customer versions: You do not need to create your own API users in the customer versions of onOffice enterprise. In the Marketplace, the API users through which your service exchanges data with onOffice enterprise are automatically created when your service is activated.

4.) Clear identification of a customer: A customer can only be uniquely identified via the combination of customer ID (customerWebId) and user ID (userId). A customer is an instance of the onOffice software that can have many users. customers are often brokerage firms and users are the brokers. The user ID alone is not sufficient.

5.) The Accounting page links to and summarizes all topics relevant to accounting and financial transactions. The remaining topics in the documentation are more relevant for developers.
