Convert Base64 or file data into PDF
Whether the source is a file or Base64 payload, type and integrity are checked before output.
Transactions for the requested period are verified, converted into a safely named PDF and sent to the correct WhatsApp conversation. Empty or failed results are never presented as a valid document.
Direct definition
Creating a PDF is the easy part. The hard part is protecting customer identity, period accuracy, document integrity and delivery outcome.
Primary source: Meta Reva product and integration documentation.

Authorised statement data from the ERP is converted into a PDF, named safely and delivered to the relevant WhatsApp conversation.
Whether the source is a file or Base64 payload, type and integrity are checked before output.
When there are no transactions, the customer receives a clear message rather than a misleading empty PDF.
Temporary delivery failures retry through a controlled queue without endless loops.
Controlled delivery

Show us how the work runs today and we will define a practical first scope together.
