Verify version compatibility for the release you will run

Compatibility is a release-level question. Record the plugin package, the exact Mautic release, the command-line and web PHP runtimes, the database engine, and any required extensions. Then separate a vendor declaration from a combination your team has actually exercised.

The official Mautic Marketplace documentation, checked September 10, 2026, tells administrators to verify a plugin’s version support before installation because the Marketplace does not perform that compatibility check at this stage. A marketplace listing or broad package constraint is useful evidence, but it is not a substitute for a staging run that matches your environment.

Two supporting references: the Mautic 7 compatible plugins guide explains the evidence sequence, while Mautic pipeline plugins compared applies a dated, vendor-source standard to sales-pipeline candidates.

Trace database tables and every other data path

For a self-hosted sales workflow, data ownership should be testable. Ask the publisher to identify the tables used for core records, relationships, history, settings, and queued work. Confirm that those tables sit in the database your team backs up, and inspect how foreign keys or identifiers connect plugin records to Mautic contacts and users.

The database is not the whole answer. Locate uploaded files, temporary exports, logs, caches, telemetry, license requests, and administrator-configured webhooks. For every path, write down what leaves the server, where it goes, why it goes there, how failure behaves, and what remains available when the destination cannot be reached.

Finish with the exit path. Verify whether disabling or removing the plugin preserves tables and files, which export formats retain relationships, and which restore steps have been rehearsed. Ownership becomes operational when your team can locate, back up, export, restore, and deliberately remove the records it depends on.

Test the API surface against real sales workflows

An “API available” badge does not tell a sales team whether its workflow is covered. Build a small matrix from the actions people and automations must perform: create and read a deal, change its stage or owner, associate contacts, preserve role labels, add follow-up context, and retrieve enough history to diagnose a failed integration.

For each required action, record the route, authentication method, request and response fields, validation behavior, pagination, permission checks, and error format. Run those calls in staging with both valid and invalid inputs. If webhooks are part of the design, test signature validation, retries, duplicate delivery, ordering assumptions, and the boundary between inbound and outbound events.

The useful question is not whether an API exists. It is whether the documented surface covers the exact records and transitions your sales process needs without forcing an operator to repair state manually.

Read the update and licensing model as operations

Licensing affects deployment architecture. Identify what is licensed—an instance, hostname, user, or another unit—and document the treatment of staging, domain changes, disaster recovery, and parallel old-and-new environments. Ask what an unreachable validation service changes for an active installation and what it changes for a new activation.

Updates need the same scrutiny. Check where release notes live, how packages are authenticated, which versions remain downloadable, whether database migrations are called out, how an administrator rolls back files, and whether that rollback also changes database state. A published update window and support window should be read beside the release history, not as a stand-in for it.

Price is a separate commercial input. The operational decision rests on the rights, dependencies, maintenance evidence, and recovery boundaries attached to the license model.

Complete pre-install verification before production

Turn the evidence review into a written staging plan. Record where the package came from, preserve its checksum, read its requirements and release notes, inventory the files and database state it can change, and take recoverable backups of each. Define who can stop the rollout and which failures trigger recovery.

Install the same package on a representative staging copy. Rebuild caches as the correct operating user, restart the relevant PHP runtime when the deployment requires it, inspect application and server logs, and exercise the sales workflows in the API matrix. Confirm permissions for both an administrator and the least-privileged role that will use the plugin.

Then rehearse recovery. Restoring earlier files does not necessarily restore an earlier schema, so prove the file, database, and uploaded-data paths separately. Production approval should point to captured results, unresolved unknowns, and a named recovery route rather than a successful page load.

Worked example: applying the checklist to Deal Flow

On September 10, 2026, I applied this checklist to Deal Flow’s published material. The compatibility evidence page records declared Mautic, PHP, database, and package constraints while distinguishing those declarations from an exact tested matrix. That distinction means an evaluator still has to test the target stack.

The security and data page states that core deal records live in the customer’s Mautic database, identifies the local attachment path, and describes what license validation, update checks, and configured webhooks can transmit. The REST API reference documents authenticated routes for deal, stage, contact, note, and task workflows. The published terms define the licensed unit, update and support window, and staging treatment.

Together, those pages answer the architecture questions without asking a buyer to infer them from a feature grid. They also leave the environment-specific work where it belongs: compare the documented surface with your requirements, test the exact stack in staging, and keep the unknowns visible until evidence resolves them.

Frequently asked questions

What should a sales team check when evaluating a Mautic plugin?

Check the plugin's declared version support, where its records and files live, which workflows its API covers, how updates and licensing affect operations, and whether installation and recovery work in staging.

How do you verify a Mautic plugin's version compatibility?

Verify the exact plugin release against the exact Mautic, PHP, and database versions you run. Treat a package constraint or marketplace listing as evidence to review, then prove the combination in a representative staging environment.

Why does database table ownership matter when choosing a plugin?

Knowing the tables and file paths lets your team back up, export, restore, retain, and remove sales records on purpose. It also reveals which data paths depend on an external service.

What should you verify before installing a Mautic plugin?

Record package provenance and requirements, back up every state the plugin can change, rehearse the install in staging, inspect logs, test critical sales workflows, and complete a recovery rehearsal before scheduling production.
