Doubts
Before you open the documentation
In full in Spanish, English and Catalan: not a translated index, all 982 pages. Same address with the prefix in front, /es/guides/quickstart or /ca/guides/quickstart. The only thing that does not change language is the code of an error.
A more connected businessNow you know where to start
The first guide on the route ends with an invoice issued and sent. Against the sandbox, without spending a single number of your real numbering.
