Your server's reply to an ipn call should be a simple text.

To indicate that the call is successful, just return this response:

OK

You may add extra data, e.g.:

OK
thankyou_url: https://www.some-domain.com/thank-you
username: some-user-name
password: a-secret-password
loginurl: https://www.some-domain.com/login headline: You access data"

By default, the access data are shown in the Digistore24 order confirmation email and on the invoice.

To not show the access data on the invoice, add a line:

hide_on: invoice

Adding multiple member accounts

If you want to create more than one membership account, just add more username/password sets. Append "_2" for the second account, "_3_" for the third, and so on.

Example:

OK
thankyou_url: https://...
username: some-user-name
password: a-secret-password
loginurl: https://www.some-domain.com/login
username_2: another-user-name
password_2: another-password
loginurl_2: https://another-url.com/login
headline: You access data"

Adding custom data

You may add any kind of data.

The response needs to start with OK.

You may add any key-value pairs.

Text needs to be plain text and cannot have HTML tags.

OK
headline: Your software
Your license key: some-key
Your software package: a package name
