Is it correct to use taxId for the CIF in the integration between Payhawk and MS Business Central?
“CIF” typically refers to a fiscal identification number. In Payhawk, the equivalent field in Spanish is Número de identificación fiscal, which corresponds to taxId in the platform.
If issues persist, contact Payhawk Support and share the exact payload you are using and a screenshot from Payhawk so you can verify the data mapping.
How can I retrieve invoices into MS Business Central once an expense has been reviewed?
Use the Expenses endpoint and filter by ReviewedAt. The filter must be encoded, and you can test it directly in the Developer Portal.
Alternatively, you can use webhooks for the expense reviewed event to trigger the data retrieval automatically.
