About Gmail and Qonto
The Gmail integration turns your inbox into an automated invoice capture flow.
The Qonto connection works on supplier invoices in both directions.
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.
Match supplier confirmations to outbound transfers
Payment confirmations arriving in Gmail from a supplier are parsed for amount, reference, and date, then matched against the next Qonto debit window. Above the auto-link threshold the bank line carries the confirmation PDF; below it the queue surfaces the candidate transfer alongside.
Catch double-charge attempts from email
If a Gmail message asks for a second payment that you have already settled out of Qonto, Well flags it before any action. The original Qonto debit is shown alongside the parsed amount and counterparty so finance can refuse the second request with one click.
Anchor inbound wire references
Inbound wire notifications in Gmail carry a free-text reference that Qonto statements often abbreviate. Well harmonises the references so the next Qonto credit collapses onto the right invoice or receivable in the downstream ledger without manual lookup.

Map your accounts
Well discovers the Gmail attachments matching your invoice pattern (invoice and receipt PDFs from email attachments, plus the sender, subject, and date headers) and the the Qonto supplier-invoices section. Tune the parsing prompt once on the first ten records; Well saves the mapping and applies it to every subsequent attachment above 85% confidence.
- Auto-post above85% confidence
- Overridemanual anytime
3Connect Qonto

How Gmail and Qonto stay secure with Well
Well calls Gmail with an OAuth 2.0 token scoped to read-only access. Gmail's consent screen lists the scopes before you approve; access tokens are exchanged and refreshed automatically before they expire. Well processes records per the storage region configured for your workspace; only fields strictly required by the write surface are ferried across regions.
- granted
Read Gmail records
Scoped to invoice and receipt PDFs from email attachments, plus the sender, subject, and date headers. No access to anything else in your Gmail account.
- granted

Frequently asked questions about Gmail and Qonto on Well
- 01How 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.
- 02What 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.
- 03How 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.
- 04Can 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.
- 05What 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.
- 06How 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 at rest and in transit under TLS 1.3. Qonto hosts in the EU and Gmail hosts outside the EU; Well processes records per the storage region configured for your workspace.
