What Well does with your Gmail connection
Connect
Connect Gmail over OAuth 2.0 (Gmail scope): you grant read-only mailbox access on Gmail's consent screen, so the password never reaches Well; Well holds only a scoped read token.
Sync
Well brings invoice email, receipt, and sender in from Gmail on a recurring poll that fetches only what changed since the last read. The first sync backfills history in the background and the connection stays live after.
Enrich
Well resolves each Gmail entity into invoice document, expense, and vendor, assigns categories, and links every record to an audit trail across the rest of your connected tools.
Available
Your data from Gmail lands in the workspace as invoice document, expense, and vendor you can search, chart, and automate.
Questions Gmail unlocks
Ask in plain language. Well answers from your connected Gmail connection, resolved against the rest of your stack.

Connect Gmail in three steps
- 01
Sign in to Gmail read-only
Choose Gmail in Well's Connections panel and sign in with Google. Well requests the gmail.readonly scope plus basic profile, which you grant on Google's own consent screen. No password or key is stored in Well; Google issues a read-only token.
- AuthGoogle OAuth 2.0
- Scopegmail.readonly (read-only)
- TransportGmail REST API
- 02
Map your entities
Well scans your inbox for messages with invoice and receipt PDFs, reads those attachments through the Gmail API, and extracts vendor, amounts, tax, dates, and line items, keeping the sender, subject, and date headers for traceability.
- Mappingpreconfigured by Well
- 03
Use the data
The extracted documents become structured records you can query, match, and route to a connected accounting destination. Gmail stays read-only throughout, so Well captures and structures but never sends or changes anything in your mailbox.
- First syncstarts as soon as connect completes
Sign-in takes about a minute. Recent mail is read first; your earlier inbox backfills in the background while you work. Gmail developer docs.
How Gmail stays secure with Well
Gmail connects through Google OAuth 2.0 with the read-only gmail.readonly scope, read over the Gmail REST API, so Well receives a token that can read messages and attachments and cannot send, delete, or label mail. Well uses it to find invoice and receipt PDFs and extract their fields; the mailbox stays untouched. Read-only is the whole grant, and there is no write path to misuse.

Frequently asked questions about Gmail and Well
Select Gmail in Well's Connections panel and sign in with Google. Well requests the read-only gmail.readonly scope plus your basic profile, which you approve on Google's consent screen. That scope lets Well read messages and attachments and nothing else; it cannot send, delete, or label mail on your behalf.
Well scans your inbox for messages carrying invoice and receipt PDFs, reads those attachments through the Gmail API, and extracts the vendor, amounts, tax, dates, and line items into structured workspace records. It also keeps the sender, subject, and date headers so each captured document traces back to the email it came from. The PDF is the payload; the headers are the audit trail.
Well's interest is messages with invoice and receipt attachments, so the documents it captures are the financial ones; ordinary correspondence is not turned into workspace records. The grant is the standard read-only mailbox scope, which is the access Gmail offers for reading mail, and Well uses it to find and extract the documents that matter, not to mine your conversations.
Well reads PDF invoices and receipts directly, and its document understanding handles scanned images and photographed paper documents as well as cleanly generated PDFs. A receipt buried in the email body or sent as an image is extracted the same way a structured PDF is. The output is a structured record regardless of how the original was produced.
Well reads recent mail through the Gmail API in the background and captures invoice and receipt attachments as it finds them, while the first connect works back through your existing inbox. Documents that have been read are queryable while the backfill continues. Gmail stays your mailbox; Well holds the extracted documents beside the rest of your records.
Disconnect Gmail in Well and the Google token is revoked, so Well stops reading your mailbox at once. Because the scope was read-only, there was never any send or change to unwind. The invoices and receipts Well already extracted stay in your workspace so past questions keep answering; ask Support if your retention policy needs them removed.
