Canonical examples
Fixed values used in every example of the documentation. Use them as a reference when reading curl samples and payloads: the same IDs appear on different pages on purpose, so that a transaction example connects to an alert example.
Default values
Section titled “Default values”IDs generated by Rapid
Section titled “IDs generated by Rapid”They all follow the same pattern, 00000000-0000-0000-0000- plus a suffix, to make it obvious they are examples. A real ID never has this format.

Transaction …042 is the same on every page: it is the one you create in Create transaction, then get, update and delete on the following pages, and it is the one the evidence points to.

Basic Auth header

Section titled “Example names and addresses”- Customer:

These values have no special meaning; they are just placeholders that stay consistent across pages. They are in Portuguese because they are the same in every language of this documentation.
