FAQ
Answers before you integrate.
What do I need to use the API?
Software that can make HTTPS requests, client credentials and your assigned environment URL. Our team will guide you through certificates and invoicing data.
Can I use it with PHP, an ERP or a CRM?
Yes. You can build an integration from any application with HTTP connectivity. Our PHP guide explains the approach; your specific integration must be implemented and tested.
Does a successful response mean the tax agency accepted the record?
Not always. A record may be pending processing. Query its status and process events before marking it accepted.
Does the AEAT approve software?
Compliance is evidenced by the producer’s responsible declaration under the regulations. This is neither AEAT approval nor a guarantee that every submission will be accepted.
