Action body format
The converter sends JSON for POST, PUT and PATCH actions. An existing form-only handler needs a compatibility check.
FOR HUBSPOT APP VENDORS & AGENCIES
Know what to change.
Before you migrate.
Know what your legacy HubSpot CRM cards need before migration—with a $750 independent source review and prioritized change/test plan.
Up to 2 cards in 1 public or unlisted app. Sanitized card definitions & response samples.
US$750 + applicable tax · One-time Stripe Checkout.
Refund before work starts if you cancel or we cannot accept the review.
Delivery within 2 business days after payment is verified, complete sanitized inputs are accepted, and we confirm the start. Source review only. We do not offer implementation, live-portal verification or production troubleshooting.
WHAT CAN CHANGE DURING CONVERSION
Will the converted card still match your backend?
An added appId
Fetch and action requests gain a parameter. Strict validators and request verification need review.
Two ticket locations
Ticket migration requires record-sidebar and Helpdesk replacement cards, with evidence for both.

A plan for your own developer.
Use the findings to decide what needs changing and what your maintainer must verify. This is not a migration build or a promise that your app is compatible.
- Supplied sanitized definitions and synthetic payloads only
- Findings separated from unknowns and proposed tests
- No customer code execution or production access
- No HubSpot platform recovery or support escalation
Your qualified developer is responsible for implementation, test-portal verification and deployment. If you need someone to build or troubleshoot the migration, this review is not that service.

REVIEW CONTENTS
- Card & endpoint inventory
- Compatibility observations
- Security & data handling flags
- Test coverage requirements
- Unknowns requiring verification
HubSpot also publishes a free legacy-card converter example. This review identifies what your supplied cards still need and which tests must establish compatibility. We do not offer implementation or live-portal verification.
START WITH THE RIGHT QUESTION
Is your card affected?
Choose what your integration uses. This check runs in your browser and sends no data.
WHAT GOOD HANDOFF LOOKS LIKE
Evidence before irreversible changes.
Your $750 review defines the changes and acceptance tests. Your own developer must implement and test the replacement; we do not offer that work.
Map the actual behavior
Legacy payloads, actions, record types, scopes, backend ownership, and customer views become a concrete inventory.
Test the replacement
Check loading, empty and error states, authorization, actions, and record context in a test portal. A local build alone is not proof of a working migration.
Confirm the production step
HubSpot’s view migration cannot be stopped or reversed. The client’s authorized administrator confirms that step after reviewing test evidence.
CHOOSE THE HELP YOUR TEAM NEEDS
A review before a build.
Free docs & guides
HubSpot’s documentation and converter example are free starting points. Blog guides add context. Your team applies them to your app.
Your app’s $750 review
Turn accepted sanitized inputs into a card inventory, prioritized source findings, test matrix and technical handoff—or a clear no-fit result. Inspect our synthetic sample first.
Your developer’s build
Your own qualified maintainer handles implementation, live-portal testing and deployment. We do not offer that work or quote a build price.
The review is a standalone purchase, not a deposit on implementation.

Useful boundaries
Are all HubSpot integrations affected?
No. The published deadline concerns legacy CRM cards. We verify the actual card surface and app model. A private app or API connection is not proof of legacy-card exposure.
Can you promise the migration is reversible?
No. HubSpot says its view-migration operation cannot be stopped or reversed. Code and configuration backups help recovery planning but do not reverse that operation.
Do you build or maintain the replacement?
No. We provide the bounded source review only. Your own qualified developer handles implementation, live testing, deployment and ongoing maintenance.
How do orders and refunds work?
Pay $750 plus applicable tax through Stripe directly from this page. We then confirm fit, complete sanitized inputs and your start date. Delivery is within two business days after start. If the review cannot be accepted or you cancel before work starts, we refund the payment. Implementation is not offered. See the service terms for cancellation and delivery remedies.
