Upload a purchase invoice or receipt
Uploads one PDF, UBL, PNG or JPG file to Inkopen for SnelStart to read.
POST https://cotlet.dev/api/v1/snelstart/purchase-documents
write
Does what dragging a file into Inkopen does. SnelStart reads the file and lists it as a purchase with status Te controleren, with the date, amount and supplier it recognised. Recognition is not 100 percent accurate, and the purchase stays on Vraagposten until a cost account is set. The upload reaches no one and books nothing final, so it does not ask for confirmation.
Parameters
| Name | Type | Description |
|---|---|---|
| file_name string required | string | File name with extension: pdf, xml (UBL), png, jpg or jpeg. |
| file_base64 string required | string | File contents, base64 encoded. |
