How does Well match Gmail records to entries in Qonto?

Well parses each Gmail attachment into a structured invoice, then probes your Qonto ledger for an open bill or vendor with the same amount, due date, and supplier name. The probe ranks candidates by counterparty proximity, date window, and total match; above 85% it links the parsed PDF to the existing Qonto entry, otherwise the parsed invoice queues for sign-off with the candidates surfaced.

What happens to historical Gmail data when I first connect to Qonto?

Gmail exposes the last full year through its API on a connected account. The window Well actually pulls is configurable from the integration settings page; each record is matched against your existing Qonto ledger, and re-running the backfill is safe because Well tracks the Gmail record IDs and updates existing Qonto entries instead of duplicating them.

How does Well prevent duplicates when posting Gmail records to Qonto?

Every Gmail message has a stable message ID, and Well stores it the moment the attachment is parsed. If the same email is reprocessed (label change, mailbox migration, or a manual rerun), Well recognises the message ID and skips the duplicate, or updates the linked Qonto entry if a downstream field changed. Forwarded copies of the same invoice are caught by counterparty-plus-amount matching before they reach Qonto.

Can I customise which Gmail fields are sent to Qonto?

The default mapping turns every parsed Gmail attachment into a Qonto-shaped record (vendor, amount, due date, tax). From the integration settings page you can adjust the parsing prompt, force a vendor mapping, attach the original PDF on a specific Qonto field, or compute a tag from your connected data. Custom mappings are versioned so a change does not retroactively touch already-posted Qonto entries.

What happens if a Gmail record fails to post to Qonto?

When a record fails to post to Qonto (validation rule, missing field, transient 5xx), Well retries automatically with backoff. Auth failures short-circuit the retry loop and notify the workspace owner; schema rejections are kept on the integration status page with a one-click retry-after-fix action pointing back at the original Gmail record. Nothing silently drops.

How does Well authenticate with Gmail and Qonto?

Gmail runs a manual OAuth 2.0 flow that you approve inside Gmail; Well receives a refresh token scoped to the resources it needs to read. For the delivery side, once a record clears the matching threshold Well posts it directly to Qonto over the connected API; the credential is held per-workspace and never exchanged across tenants. Tokens are encrypted in transit under TLS 1.3. Anything Well holds between Gmail and Qonto is encrypted at rest and handled in line with GDPR.

Gmail

Source

The Gmail integration turns your inbox into an automated invoice capture flow.

Qonto

Target

The Qonto connection is Qonto's MCP server, approved over Dynamic Client Registration, and it carries offline_access, organization.

Why this pair

Suppliers email invoices as PDF attachments, and Qonto exposes a separate supplier-invoice upload path that is not linked to the bank transaction by default.

Connecting Gmail to Qonto through Well uploads each emailed invoice to Qonto's supplier-invoices via the /v2/supplier_invoices/bulk endpoint, then reconciles it inside Well against the eventual bank-line outflow so one record carries both the invoice and the payment. Gmail pushes new message events to Well via Pub/Sub; Well POSTs the supplier invoice PDF to Qonto over OAuth at that cadence.

What Well does with Gmail invoices on the way to Qonto.

01Featured

Capture an invoice from email

Well reads an invoice PDF from a Gmail attachment with its sender and date, so the document is ready to match.

Match against Qonto invoices

Well reads the supplier invoices and attachments from Qonto and matches each to the invoice from Gmail, so the supplier is resolved.

Keep the email trail

The sender, subject, and date from Gmail stay attached to the matched document, so each invoice traces to its message.

One document, not copies

When the same invoice arrives twice in Gmail, Well keeps one before matching, so Qonto records do not double up.
