Automation platforms
Zapier integration services
Zapier integration services connect your apps so data flows without re-keying. The work that matters most is unglamorous: a field map you can check, lookups that stop duplicates, formatting so data fits the destination, secure handling of webhooks for apps without built-in connections, testing that checks the destination app rather than just Zapier's history, an estimate of task use and app connections under your business accounts. Asking how a provider handles each of these tells you more than a list of apps it has connected.
This page covers stages, responsibilities, what you should receive, warning signs and support. LetGetGrow builds, fixes and migrates automations in n8n, Zapier and Make, with the scope, cost and timeline set out in a custom quotation.

Output: Integration list
Field map
Fields, formats, matching rules.
Output: Approved map
Build
Lookups, formatting, filters, actions.
Output: Draft Zaps
Testing
Checked in destination apps.
Output: Test evidence
Handover
Notes, alerts, task estimate.

The field map
Ask for a table listing each field, where it comes from, where it goes, how it is formatted and what happens if it is empty, plus the field used to match existing records. Approving it before build catches misunderstandings early and gives your team a reference later.
Who does what
| Task | Usually |
|---|---|
| Zapier and app accounts | Client owns |
| Field map draft | Provider |
| Approving matching rules | Client |
| Build and testing | Provider |
| Responding to failure alerts | Client, trained |
Warning signs
Creates records without lookups
Duplicates build up.
Testing only in the Zap editor
Data may land wrongly in the destination.
Public webhook URLs shared freely
Anyone could send data.
No mention of task use
Plan costs may rise unexpectedly.
Testing in the destination
A Zap run can succeed while the data lands in the wrong field or format. Ask the provider to check sample records in each destination app and share screenshots or notes, including cases with missing fields and existing customers. Ask what happens when the destination app is briefly unavailable.
Example: an integration brief
Illustrative example — not a client case study
Situation: A property management firm wants maintenance requests from a form to reach its job system and notify contractors.
- The provider drafts a field map, matching properties by reference number.
- Tests include a request for an unknown property and one with photos attached.
- Results are checked in the job system, and failure alerts go to the office team.
What this shows: Requests flowed into the job system reliably, with unknown properties flagged rather than mis-filed. This example is illustrative.
What you should receive

- Edge case results
Operations
- Monthly task estimate
- Alert and connection list
Apps without built-in connections
For apps reached through webhooks or API requests, ask how authentication is stored, how incoming webhooks are verified and how errors are handled. These steps carry more responsibility than built-in connections.
Support
Ask how quickly the provider responds if an integration breaks and whether small changes are covered. Apps update, and integrations need occasional attention. Ask for a log of changes made after launch.
Briefing the provider
List the apps, what should flow, which app is the source of truth for each field, expected monthly volumes and who should receive failure alerts. Mention any existing Zaps that touch the same apps.
Discovery
A good provider asks which apps are involved, what should flow and when, which app owns each piece of data, how many records move each month and who should be told when something fails. It should also ask about existing Zaps that touch the same apps, since overlapping automations are a common cause of duplicates and loops. The answers shape both the design and the task estimate.
Duplicate prevention
Ask how the provider will prevent duplicate records: which field it will match on, what happens when a match is found and what happens when the matching field is missing. Duplicates are one of the most common and most annoying integration problems, and they are much easier to prevent than to clean up.
Task estimate
Ask for an estimate of monthly task use per integration, based on expected volumes and the number of action steps after filters. It helps you choose a plan and spot designs that use more tasks than necessary.
What to agree
Agree scope, field maps, acceptance testing, account ownership, support terms and how changes are requested and priced.
Formatting for the destination
Ask how dates, phone numbers, currencies, names and picklist values will be formatted so they fit each destination app. Small mismatches cause failed actions or messy data, and are cheap to handle in the design.
