How to integrate Unify with AWS Lambda

To integrate Unify with AWS Lambda, send a Play webhook to a custom HTTPS handler that your team deploys. That handler validates the request and performs the operation you implement. Use this connection to receive prospect data in an AWS Lambda function you own.[1][2][3]

At a glance

  1. Custom webhook: AWS Lambda receives the handoff
  2. POST request with an explicit JSON contract and destination authentication
  3. Test scenario: Choose the authentication boundary

When this workflow makes sense

Start with the decision your team needs to make, then choose the connection that supports it.

A small receiver can connect Unify to systems that require AWS credentials or custom rules. Keep its responsibility narrow: authenticate the source, validate the contract, and persist or dispatch one operation. Use the execution role for AWS access instead of placing AWS keys in the Play.

A good fit when

Teams that want to receive prospect data in an AWS Lambda function you own and have an owner for the receiving process. A developer or automation owner must maintain the receiver and its credentials.

Reconsider the plan when

There is no owner for the receiver, credential lifecycle, or recovery process. Assign that responsibility before using AWS Lambda for a live handoff.

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.

StageDecision to make
Business decisionReceive prospect data in an AWS Lambda function you own
Receiving contractAgree which of the 5 example data fields the receiving process actually needs. Set missing-value and identity rules in the field mapping below.
Execution boundaryAssign an owner for the HTTPS receiver, credentials, and AWS Lambda operation.
CompletionDecide who can confirm the AWS Lambda outcome and recover a failed or repeated handoff. Use the completion check below as the acceptance criterion.

Receive prospect data in an AWS Lambda function you own

Start with one controlled record and one intended AWS Lambda outcome. Keep the test destination separate from live operations.

The decision that matters

The receiving owner must distinguish accepted input from completed work. Agree on the evidence required before treating this handoff as successful.

  1. Prepare the destination using the AWS Lambda setup checklist
  2. Resolve the sample fields for one known record and inspect the request before sending it
  3. Trace that handoff through the receiving operation and compare the actual destination values with the source

Choose the authentication boundary

Choose the authentication boundary: compare an application-secret receiver with an IAM-protected URL. Test the actual selected path and document which component signs requests when IAM is required.

The decision that matters

Decide whether this case should be held for review, corrected, or retried. Make that decision before running AWS Lambda against live records.

  1. Isolate the test in a controlled destination and record the starting state
  2. Run the edge case described above and capture the actual response and destination state
  3. Recover the record once, then check that recovery did not create unintended additional work

Expected, not tested

Receive prospect data in an AWS Lambda function you own

Inspect the function invocation and the actual destination record or queued job result. Test an invalid secret and confirm that no work is accepted.

Questions answered

Common decisions when connecting Unify and AWS Lambda.

Can a Bearer token call an AWS_IAM Function URL?

No. AWS_IAM Function URLs require AWS Signature Version 4. Use a signing intermediary or an application-authenticated handler under the appropriate Function URL configuration.[3]

Limits & decisions

Check these boundaries before designing a live workflow around the connection.

  • A Function URL is only an HTTP entry point. Request validation, deduplication, storage, and business logic are code your team must implement.[3]
  • The receiver and downstream logic are implementation work, not a hosted endpoint or installed connector supplied by this article.[3]

Connection requirements and setup checklist

Before connecting

  • A Unify Play with a Webhook action and a controlled record for testing
  • Access to the intended AWS Lambda environment and the permissions required by the cited API or trigger
  • An HTTPS receiver your team implements or configures, with an owner and a place to inspect accepted work
  • An agreed record identity, duplicate policy, and owner for failed handoffs
  1. Prepare the AWS Lambda destination

    Implement a handler that checks the incoming secret, validates JSON, and performs a narrowly scoped operation using the function execution role.[3]

  2. Implement the receiving operation

    Create a Function URL and choose its authentication model. For slow work, durably enqueue the handoff and return promptly, then monitor the worker result.[3]

  3. Configure the Unify request

    Use POST, the endpoint and authentication below, and JSON body format in the Webhook action. Replace setup placeholders, then inspect Expand preview with a controlled record. The receiver must respond within 8 seconds; webhook response bodies are not exposed to later Play steps.[1][2]

  4. Validate the complete handoff

    Run the success and edge-case scenarios in Explore the scenarios with a controlled record. Save the request identity and destination evidence, then apply the completion check before enabling live traffic.[3]

Request configuration

Method
POST
URL pattern
https://YOUR_FUNCTION_ID.lambda-url.YOUR_REGION.on.aws/
Headers
Content-Type: application/json
Authorization: Bearer YOUR_RECEIVER_SECRET
Authentication
For a direct Unify request, use a Function URL whose handler validates an application Bearer secret before any side effect. AWS_IAM mode instead requires SigV4 signing and an intermediary; a static Bearer token does not satisfy IAM.

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
Example request body
{
  "event": "prospect_handoff",
  "handoff_id": "example-handoff-001",
  "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.

Proposed JSON contract for your receiver, not a ready-made destination API request. Implement the translation in Technical setup. All prospect values are fictional and all setup placeholders must be replaced. 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.[1][2][3]

Payload fieldValue to send
eventstring / static / Request configurationKeep the literal "prospect_handoff" required by this example request; change it only when deliberately changing the receiving contract.

If missing: Keep this configured value in the request; do not replace it with a blank prospect field.

handoff_idstring / dynamic / Handoff identity chosen by your implementationSupply a stable identifier for this logical handoff. Reuse it on a retry, and use a different identifier for a genuinely new event. Do not assume Unify automatically creates this sample field.

If missing: Hold the handoff until the receiver or upstream workflow can establish its identity.

prospect_namestring / dynamic / Full nameSelect the available full name field for the controlled person or company record in Unify. Keep the receiving field a string.

If missing: Skip or hold the handoff if this value is required by the destination; omit it only when the destination contract permits omission. Do not send a guessed value.

prospect_emailstring / dynamic / EmailSelect the available email field for the controlled person or company record in Unify. Keep the receiving field a string.

If missing: Skip or hold the handoff if this value is required by the destination; omit it only when the destination contract permits omission. Do not send a guessed value.

company_namestring / dynamic / Company nameSelect the available company name field for the controlled person or company record in Unify. Keep the receiving field a string.

If missing: Skip or hold the handoff if this value is required by the destination; omit it only when the destination contract permits omission. Do not send a guessed value.

company_domainstring / dynamic / Company domainSelect the available company domain field for the controlled person or company record in Unify. Keep the receiving field a string.

If missing: Skip or hold the handoff if this value is required by the destination; omit it only when the destination contract permits omission. Do not send a guessed value.

Function URL requests use the API Gateway payload format version 2.0. Parse event.body and handle isBase64Encoded when applicable before reading prospect fields.

Troubleshooting

Start with the stage where the expected data or action stops appearing.

The request is rejected

For a direct Unify request, use a Function URL whose handler validates an application Bearer secret before any side effect. AWS_IAM mode instead requires SigV4 signing and an intermediary; a static Bearer token does not satisfy IAM. Check the receiving account, permissions, endpoint, and required fields against the cited documentation.[3]

The values or destination are wrong

Compare the resolved JSON with the field-by-field contract in Example handoff payload. Check identifiers against the selected AWS Lambda environment, and distinguish an absent source value from an intentional static value. Fix the mapping before repeating the write.[3]

Receipt does not match the expected result

Find the request in the receiving logs, then inspect the actual AWS Lambda resource or execution. If the request was accepted but no result exists, investigate the destination failure before retrying. Keep the same logical handoff identity when recovering a repeat.[3]
