Interface Contract

An Interface Contract is a bilateral agreement between two specific systems defining exactly what data they exchange: fields, formats, required values, update rules and error behavior.

It is narrower than a general data contract, which governs schema expectations across an organization; here the agreement binds one sender and one receiver.

A practical example

Label: hypothetical.

Marketing and IT agree that the lead object sent to the CRM must contain email, company, source campaign ID and consent flag, with email as the required unique key and unknown values rejected rather than defaulted.

What to evaluate before investing

  • Does the contract list required versus optional fields and their formats?
  • Does it define behavior for missing, malformed or duplicate records?
  • Is there a versioning and change-notice process when either side needs new fields?

Limitations and tradeoffs

Contracts only hold if enforced by validation at the boundary; an unenforced contract is just a wish.
