Record types

Marketo records to discuss.

These Marketo record examples help scope a technical review. They are not a list of verified Stacksync operations.

Leads
Retain the lead ID and record its relationship to any converted contact or company.
Companies
Retain the source company ID and the destination customer/company ID. Separate legal entities, subsidiaries, and business units; a shared name or web domain is insufficient.
Opportunities and Opportunity Roles
Keep the opportunity/deal ID separate from any later order or invoice ID.

Custom Objects
Identify this record type and the operation you need to review with Stacksync.
Activities and Lead Changes
Keep the source event ID, source system, occurrence time, and ingestion time. Use an explicit duplicate-detection key.
Static Lists
Identify this record type and the operation you need to review with Stacksync.
Connection setup

Marketo connection requirements.

Review Marketo access and the operations your workflow needs with Stacksync. The vendor API reference below can help your administrator prepare for that discussion.

Prepare access and scope for the engineering review
  • Identify the Marketo account, edition, environment, and business objects the integration must access.
  • Confirm a Stacksync connector or implementation path for Marketo, including read/write support, authentication, and initial-load limits.

Integration design

Match records and fields for your Marketo integration.

Assign authority for consent, audience membership, campaign state, and analytical results separately. Define how removals and opt-outs reach every relevant destination.

Use these design questions to prepare a representative record and the business rules your integration must preserve.

Mapping checks by record type

Leads

Confirm object support with Stacksync

Identity
Retain the lead ID and record its relationship to any converted contact or company.
Fields to consider
Source lead ID · Qualification status · Owner reference · Conversion reference
Related records to resolve first
Resolve owner and campaign references and decide how conversion changes the identity relationship.
Test before going live
Convert a test lead after the first load and verify that it does not create a duplicate person or orphan its activity.

Companies

Confirm object support with Stacksync

Identity
Retain the source company ID and the destination customer/company ID. Separate legal entities, subsidiaries, and business units; a shared name or web domain is insufficient.
Fields to consider
Source record ID · Legal or display name · Business-unit reference · Lifecycle status
Related records to resolve first
Resolve parent organizations, business units, and currency references before dependent transactions.
Test before going live
Use two organizations with similar names and one with multiple business units. Verify that an update reaches the intended entity only.

Opportunities and Opportunity Roles

Confirm object support with Stacksync

Identity
Keep the opportunity/deal ID separate from any later order or invoice ID.
Fields to consider
Source deal ID · Stage · Amount and currency · Expected close date · Company reference
Related records to resolve first
Map the customer and sales pipeline before the opportunity; map stage values deliberately.
Test before going live
Test a reopened won deal, a stage with no destination equivalent, and an amount using a different currency.

Activities and Lead Changes

Confirm object support with Stacksync

Identity
Keep the source event ID, source system, occurrence time, and ingestion time. Use an explicit duplicate-detection key.
Fields to consider
Source event ID · Event type · Occurred-at time · Related record ID · Payload version
Related records to resolve first
Resolve the related customer, user, or transaction identity without assuming the event ID is the entity ID.
Test before going live
Deliver the same event twice, then an older event after a newer one; verify duplicate and ordering behavior.

Programs and Program Members

Confirm object support with Stacksync

Identity
Keep campaign ID, channel/account context, and separate audience membership IDs.
Fields to consider
Source campaign ID · Channel reference · Status · Audience references · Measurement window
Related records to resolve first
Resolve contact/audience identities and channel-account references.
Test before going live
Test a removed audience member, a paused campaign, and one campaign reported across multiple channels.

Download the field-mapping workbook (CSV) to capture the actual API fields, matching keys, owners, and test results. Use it as you build with your team or a Stacksync engineer.

Setup and validation

Validate the Marketo integration in four steps.

An opted-out person remains excluded after a profile update, and campaign results reconcile for the same channel and measurement window.

View the four setup tests and expected results

  1. Confirm the intended Marketo account and grant

    After confirming an implementation path, validate the selected access method with the intended account and environment. Check that the authorizing user can grant access to the selected objects; test reauthorization without changing the mapped record identity.

    Expected result: The connection reaches the intended account, and the integration owner can renew or revoke the grant through the agreed procedure.

  2. Test record matching for Leads

    Using the implementation established in the compatibility review, preserve the selected source ID and resolve the required references. Convert a test lead after the first load and verify that it does not create a duplicate person or orphan its activity.

    Expected result: An opted-out person remains excluded after a profile update, and campaign results reconcile for the same channel and measurement window.

  3. Test the operation your workflow needs

    Review one Marketo record with a Stacksync engineer. Confirm how it should reach the other system, how often it must update, and whether your workflow needs reads, creates, or updates. Test those operations before expanding the integration.

    Expected result: The selected operation is confirmed, addresses the intended record, and exposes rejected values for repair.

  4. Test recovery and name the support owner

    For the confirmed implementation, interrupt a non-production transfer and restore access. Establish whether recovery uses the current source state or a stored historical event, and verify that repeated delivery preserves record identity.

    Expected result: The records have the expected current values, repeated delivery creates no duplicate business record, and your team knows who handles unresolved errors.

Use the production-readiness checklist to record test results, assign support owners, and agree on when to go live.

Troubleshooting

Troubleshoot your Marketo integration.

Diagnose record matching, delayed changes, and rejected operations
A Marketo record appears under the wrong destination record
Retain the lead ID and record its relationship to any converted contact or company. Resolve owner and campaign references and decide how conversion changes the identity relationship. Repair the ID relationship before repeating the operation.
The first load looks correct but later results differ
Confirm the selected Marketo implementation’s change-detection method for Leads, Companies and Opportunities and Opportunity Roles. Compare later changes with the original source rather than using a successful initial copy as evidence of ongoing capture.
One operation succeeds while another is rejected
Check the specific Marketo object, field permissions, required references, and allowed operation. A successful read does not establish that a create, update, deletion, or business action is available.

Review retry, replay, and recovery behavior before repeating an operation that may already have succeeded.

FAQ

Marketo connector FAQ

How should I plan an integration with Marketo?

Assign authority for consent, audience membership, campaign state, and analytical results separately. Define how removals and opt-outs reach every relevant destination. Confirm the connection and read/write operations with Stacksync. Start with one workflow, agree on which fields each system owns, then test initial data, later changes, and recovery before expanding.

Can the Marketo connector write changes back?

Write-back support is not established for this connection. Review the Marketo records and fields you need with a Stacksync engineer, then test the required operation with a representative record.

Which identifiers should I preserve for Marketo data?

Retain the lead ID and record its relationship to any converted contact or company.

Which related records should I load first for Marketo?

Resolve owner and campaign references and decide how conversion changes the identity relationship.

How do I validate Marketo changes after the initial load?

Convert a test lead after the first load and verify that it does not create a duplicate person or orphan its activity. An opted-out person remains excluded after a profile update, and campaign results reconcile for the same channel and measurement window.

What will we cover in a Marketo integration demo?

Start with one workflow and a sample record from Leads, Companies and Opportunities and Opportunity Roles. We can review how to identify the record, connect related data, set the update direction, and test recovery. Include the person who owns the source system and anyone who will maintain the integration; you do not need a finished requirements document.
