How to integrate Unify with Neon
To integrate Unify with Neon using the serverless driver, send a Play webhook to an external HTTP endpoint, such as a Vercel Function. That endpoint validates the prospect and uses the driver to execute parameterized SQL. The database client and the webhook receiver are separate parts of this architecture.[1][3][4]

When this workflow makes sense
Start with the decision your team needs to make, then choose the connection that supports it.
A database handoff should answer a business question: are you storing the latest state of a prospect, or a history of separate events? Those models need different keys and different rules for repeated delivery. Decide what a row means before choosing the SQL operation. Otherwise, the same prospect can become duplicate work or a later update can overwrite useful history.
A good fit when
Teams with an application backed by Neon Postgres that need selected prospect facts in their own schema and can maintain the HTTP receiver.
Reconsider the plan when
A database table by itself does not assign an owner or perform a sales action. Choose who or what uses each saved row, and avoid treating an append-only event log as a current prospect record.
Design the handoff
Use this framework to agree on the input, the next action, and who owns the result.
Suggested workflow design, based on the documented capabilities below.
| Stage | Decision to make |
|---|---|
| Receiver | Send Unify to an external HTTPS handler that owns authentication and validation. |
| Identity | Decide whether a row represents a person, company, or distinct handoff. |
| Persistence | Use fixed columns, parameterized values, and a deliberate uniqueness rule. |
| Consumption | Name the application or person that uses the saved data and checks failures. |

Maintain the latest prospect snapshot
An internal application needs the current set of selected prospect facts in Postgres.
One row should represent one agreed identity. Decide which incoming fields can replace existing values.
- Choose the identity and matching unique constraint
- Implement a parameterized write through the HTTP receiver
- Send a sample twice with one changed fact and inspect the row
Record distinct handoffs for review
The team needs to distinguish separate business events from delivery attempts.
A prospect identity alone cannot identify a distinct event. Only use this design when a stable handoff identity is available across retries.
- Define what makes two handoffs different and where their identities come from
- Implement event uniqueness without using the static event label as the key
- Compare a repeated delivery with a genuinely distinct handoff
Illustrative workflow, not a preconfigured automation. Complete these checks in your own account.
Define success before launch
Inspect the data and the intended outcome separately. Connection status is only the first check.
Expected, not tested
The external handler saves the fictional prospect to the intended Neon table, and a repeated handoff follows the chosen conflict rule.
Inspect the committed row in the same branch and database used by DATABASE_URL. A receiver log showing parsed JSON is not proof of a successful database transaction.

Questions answered
Common decisions when connecting Unify and Neon.
Can I send the prospect JSON directly to the Neon serverless driver?
The driver is a JavaScript database client used by your code. For this architecture, a separate HTTP endpoint receives and validates the prospect JSON before issuing SQL through the driver.[3]
Does the external receiver have to run on Vercel?
Vercel is the example host in this article. Choose a server-side runtime compatible with the Neon driver and implement the HTTP receiver there.[3]
How do I keep incoming values out of SQL syntax?
Use the driver’s tagged-template query function or a parameterized query. Keep identifiers controlled by your application rather than accepting table or column names from the webhook.[3]
How can I avoid a second row on a repeated handoff?
Choose a stable identity, enforce the matching unique constraint, and implement an intentional ON CONFLICT action. The correct key depends on whether you store prospects, companies, or events.[6]
Will the inserted row or query result be available later in the Unify Play?
No. The outbound webhook does not pass its response body to later Play steps. Design and verify a separate supported return path if the process needs one.[2]
Limits & decisions
Check these boundaries before designing a live workflow around the connection.
- This is a custom endpoint and database pattern, not a native Unify connector
- The external receiver must handle authentication, validation, errors, and response timing
- Database credentials belong only in the server-side receiver configuration
- The sample defines no table schema or automatic synchronization policy
- No live database writes or end-to-end runs have been performed
What the connection supports
Understand the connection, the data involved, and the behavior that matters for a Unify + Neon workflow.
POST / JSON to Vercel, then parameterized SQL to Neon
| Decision | What to know |
|---|---|
| HTTP entry point | The proposed Vercel Function receives the Unify request[4] |
| Database client | The Neon serverless driver executes queries over HTTP or WebSockets[3] |
| Values | Tagged templates or parameterized queries separate SQL from incoming values[3] |
| Destination | The connection string identifies a database, branch endpoint, and role[5] |
| Conflicts | Postgres ON CONFLICT uses a unique or exclusion constraint as applicable to the chosen action[6] |

Connection requirements and setup checklist
Before connecting
- A Unify Play with a Webhook action
- An external HTTP receiver and a developer responsible for its implementation
- A Neon database, destination table, and database role with only the required permissions
- A DATABASE_URL stored in the receiver environment and a separate webhook secret
Choose the row and its identity
Define a prospect table with the fields you need. Choose whether identity means a person, company, or individual handoff. Add the appropriate unique constraint and decide which incoming values may update an existing row.[6]
Implement conflict handling
For a table with an appropriate unique constraint, use INSERT ... ON CONFLICT with a deliberate action, such as updating selected facts or keeping the existing row. Check the SQL result before reporting that persistence succeeded.[6]
Request configuration
- Method
POST- URL pattern
https://YOUR_APP.vercel.app/api/unify-to-neon- Headers
Content-Type: application/jsonX-Unify-Webhook-Key: YOUR_WEBHOOK_SECRET- Authentication
- Suggested custom authentication: implement a check for X-Unify-Webhook-Key in your receiver and store the expected value as a server-side secret. In Unify, choose API Key (Header), use that header name, and enter the matching value. The header name is chosen for this example; the platform does not validate it automatically.
Choose JSON as the body format. Unify sets Content-Type automatically. The receiver must respond within Unify’s 8-second timeout; request responses are not passed to later Play steps.[2]
Replace URL placeholders with the actual receiver URL from your account or deployed application. These example URLs are not working endpoints.
Example handoff payload
Start with a fictional prospect. Validate the resolved values before using a real record.
Inspect the sample payload and field mapping
{
"event": "prospect_handoff",
"prospect_name": "Alex Morgan",
"prospect_email": "alex@example.com",
"company_name": "Example Company",
"company_domain": "example.com"
}Fictional data. Replace sample values before using a real Play.
The keys are an example handoff format, not required Unify field names. Use the field mapping to distinguish record data from fixed settings. Select available fields in your Play and inspect Expand preview; do not replace configuration values with prospect data.[2]
| Payload field | Value to send |
|---|---|
event | A fixed label you choose for this workflow |
prospect_name | Use {{ person.first_name }} and {{ person.last_name }} for the prospect name |
prospect_email | Use {{ person.email }}; decide how to handle missing values |
company_name | Use {{ company.name }} |
company_domain | Use {{ company.domain }} |
Map the JSON properties to fixed SQL columns in your receiver. Parameterize values and keep table and column names controlled by your code. The sample event string identifies the kind of handoff; it does not uniquely identify a person or a delivery.
Troubleshooting
Start with the stage where the expected data or action stops appearing.
The webhook URL looks like a database connection string
Point Unify at your external HTTPS receiver. Keep the Postgres connection string inside that receiver; the serverless driver uses it to connect to Neon.[3][4]
The write lands in the wrong database
Check the branch, database, and role selected when copying the Neon connection string, then compare the environment assigned to the actual deployment.[5]
Retries create duplicate or unexpected rows
Review the unique constraint and ON CONFLICT action. Confirm the business identity is stable across repeated requests and that application-owned fields are not unintentionally overwritten.[6]
