Replacing a CRM connector? Verify how offline sales reach Google Ads

For Colorado businesses that advertise online and close sales by phone or through sales staff, replacing a CRM connector deserves a separate measurement sign-off. The practical question is whether the replacement can deliver offline sales to Google Ads—and what evidence shows those sales are being attributed.

Google expressly documents offline imports for these sales processes. Its developer guidance also describes a restriction effective June 15, 2026, on new adoption of the legacy Google Ads API upload route, directing affected uploaders toward Data Manager. Established integrations were not universally switched off that day.

The consequence for a vendor handoff is straightforward: require the incoming provider to demonstrate its upload route and eligibility before approving the transition. This is an acceptance-testing recommendation for Colorado advertisers using these workflows, rather than a separate Colorado platform requirement.

Confirm the replacement connection's access

Start by asking which public Google interface will receive the sales records. Have the provider identify whether it will use Data Manager or an eligible legacy connection, and explain the basis for that access.

Google's official guidance leaves a point requiring care: historical eligibility windows differ across its published materials. Its Help Center acknowledges legacy allowlisting. Advertisers should therefore seek confirmation for the proposed integration rather than infer eligibility from a general migration notice or the fact that the outgoing connection worked.

Data Manager's offline-conversion capability is itself established. Google's release notes place it in the August 6, 2025, version 1.2 entry. The June restriction should be treated as a previously announced access change, not a newly launched measurement capability.

Separate submission from attribution

A connector's completed-export message should be only one part of the handoff evidence. Google's legacy offline-upload documentation explicitly warns that a successful import response does not necessarily establish that conversions were attributed, and directs users to diagnostics.

Recommended acceptance criteria should distinguish three questions:

• Submission: Which records did the replacement connection send, and when?
• Processing: What errors or warnings appeared, and which records need investigation?
• Reporting: What resulting conversion reporting can the provider show, and how does it explain discrepancies?

Ask the outgoing and incoming providers to document these checks for an agreed reporting period. Avoid requiring every exported sale to appear as an attributed conversion without explanation. The purpose is to establish a traceable account of the records and their outcomes. Google's warning about legacy responses should also not be assumed to describe every response from a different API.

Make warnings visible to the advertiser

Data Manager API version 1.8, dated July 30, 2026, added field-level warnings to event and audience ingestion responses. That provides a concrete question for a prospective connector provider: does its interface expose those warnings, and who reviews them?

The release notes establish that the warnings exist. They do not establish that any particular vendor displays them. Request a demonstration of warning visibility and an explanation of how unresolved items will reach the advertiser.

Assign ownership before approving the switch

Google also describes automatic migration of existing enhanced-conversions users to a unified setting. An account-setting migration should be reviewed separately from evidence that the replacement CRM uploads are functioning.

Before approval, name the person responsible for investigating discrepancies, the person authorized to change the connection, and the advertiser's final sign-off owner. Retain the access confirmation, diagnostic evidence and reporting review together. These are recommended operating controls, not additional Google mandates. They give a Colorado business a specific basis for accepting the handoff while keeping unresolved measurement questions visible.
