Connecting systems multiplies whatever process you already have, including its faults. An api ready marketing workflow means getting the records, identifiers and error handling right first, so integration accelerates good practice rather than bad.
Structure before connection
Integrations need consistent inputs. If orders arrive in free text and services are named differently by different people, an interface has nothing dependable to map onto, and the integration inherits every ambiguity that was previously absorbed by a human.
Fix the vocabulary first: one name per service, one format per request, one identifier per record. This is unglamorous work and it determines whether any later automation is reliable.
Getting ready
- One canonical name for every service you offer.
- A stable identifier on every record that other systems can reference.
- A consistent request format, whatever channel it arrives through.
- Defined statuses with unambiguous meanings.
- Decided behaviour for every failure case.
- Retry rules that cannot produce duplicates.
- Human checkpoints where the consequences justify them.
- Logging that records what was sent and what came back.
Duplicate prevention deserves particular attention. A retry that resubmits an order is a costly and common failure, and it is far easier to design against than to clean up afterwards.
Keep humans where they matter
Automate the repetitive and the reversible. Keep a person in the loop where an action is customer-facing, costly, or hard to undo — sending, publishing, refunding, or anything that changes a public page.
Handle credentials carefully. Keys belong in secure storage, never in messages or documents, and they should be rotated when anyone with access leaves. An integration is only as safe as the least careful place its key has been copied to. Record structure sits in the order management workflow, and planning in the marketing automation planning guide.
Common questions
What should be automated first?
Record-keeping and status updates. Automating customer communication before records are reliable multiplies errors.
How should failures be handled?
Fail visibly. Silent failures are discovered by customers, which is the most expensive way to find them.
Where do human checkpoints belong?
Anywhere an action is hard to reverse or reaches a customer directly.
How are keys managed?
Secure storage, least privilege, rotated on staff changes. Never in chat or documents.
What should be logged?
Request, response, timestamp and outcome. Enough to reconstruct what happened without guessing.
Is integration always worth it?
Only above a volume that justifies it. Below that, a clear manual process is cheaper and easier to change. See the services page.
Who should own an integration?
A named person who understands both the process and the system. Integrations without an owner are discovered to be broken by whoever is unlucky.
