PROPOSED PROJECT

API Update Checker

Help developers update software when an API—the connection between systems—changes. Compare the old and new instructions and sample code, list what needs changing, and test suggested fixes in a separate test environment.

API UPDATE / ILLUSTRATIVE REVIEW

A small change. Three places to check.

API = the connection between systems
Fictional billing service · v1 → v2
OLD RESPONSE / V1
GET/v1/invoices
{
  "id": "INV-041",
  "amount_cents": 42000
}

The amount is a single field, expressed in the smallest currency unit.

NEW RESPONSE / V2
GET/v2/invoices
{
  "id": "INV-041",
  "amount": {
    "minor": 42000,
    "currency": "PHP"
  }
}

The amount moves inside a named group and arrives with its currency.

Source value42,000minor units / PHP
Expected display₱420.00Keep the amount and currency together
Fictional API instructions, responses, and test results. This shows a proposed review workflow; no external service or customer code has been modified.

Find what breaks
before the update ships.

A fictional billing integration moves from /v1/invoices to /v2/invoices. The old amount_cents field becomes amount.minor with a currency value, and numbered pages become a returned cursor. The example maps those changes to three client files, keeps 42,000 PHP minor units displayed as ₱420.00, and checks that two sample pages return all three invoice IDs. The displayed test report is illustrative, not a live vendor result.

WHAT IS USUALLY DONE

Developers read the new API instructions, search their code for old fields, and update the obvious request. Less visible consumers can be missed: a report still reads the old amount, or a list stops after the first page. Code can look correct while silently returning incomplete results.

WHAT SOVRUN CAN DO FOR YOU

Sovrun would build an update review workspace for one supplied integration. It compares old and new API instructions, sample responses, and the code that uses them. Code-aware models propose affected locations and draft changes with source references. The workflow then runs agreed checks against sample responses or an authorized test service, packages the suggested patch with observed results, and leaves release decisions with the engineers.

Follow the change
into the places that use it.

A renamed field can affect a screen, an export, and a calculation. The proposed checker compares supplied API instructions with the client’s code, then ties each suggested change to a specific test.

01 / CONNECTION

Call the new route.

/v1/invoices/v2/invoices

Review the request in billing-client.js. Confirm the expected record can be read in the separate test service.

02 / AMOUNT

Read the new field.

amount_centsamount.minor

Update invoice-total.js and retain the supplied currency. An absent amount must show an error, not a zero total.

03 / MORE RESULTS

Follow the next page.

page=2cursor=page_2

Update invoice-list.js to use the returned page marker. Stop when no next marker is supplied.

ILLUSTRATIVE TEST REPORT / SUPPLIED SAMPLE RECORDSCheck behavior, not just syntax.
CheckOld client + v2Proposed update + v2
Read an invoiceOld route rejectedExpected record returned
Display the amountOld field missing₱420.00, with currency
Read every pageSecond page missed3 distinct invoice IDs

These examples cover the supplied records only. Live-account permissions, response limits, and other consumers still need their own tests before release.

A change list
with evidence behind it.

The first build covers one integration, its supplied old and new instructions, and an agreed set of client files. Engineers receive changes they can inspect and run in their own test environment.

THREE CHANGES TO REVIEW

Know where to look.

Request route
billing-client.js
Amount display
invoice-total.js
Page handling
invoice-list.js
01 / An affected-code reportEach change points to the source instruction and the client file that depends on it.
PATCH / ENGINEER REVIEW

Preserve the value.

amount.minor / 100₱420.00Missing amount → explicit error

No changes merged or released automatically.

02 / A proposed code updateA reviewable patch and tests in a separate branch, with unresolved questions kept visible.
PAGING EXAMPLE

All three records.

Page 1INV-041 · INV-042
Page 2INV-043

Next marker: none. Stop here.

03 / A test evidence packInputs, expected outputs, observed results, and tests still needed before an engineer approves release.

How we’d make it happen.

  1. Compare the contract and the code

    Identify changes in routes, fields, units, errors, and page handling. Follow each change to the client files that use it and record the supporting source passage.

  2. Draft and test in isolation

    Prepare a focused patch and run only agreed checks against supplied records or an authorized test service. Retain failures and unsupported assumptions in the report.

  3. Review before release

    An engineer reviews the patch, test evidence, and untested cases. Merge and release through the team’s existing process only after the outstanding checks are resolved.

Where AI helps

Language and code models read the supplied API instructions, follow field use through the agreed client files, and propose focused patches and tests. We compare models on missed dependencies, unsupported changes, and behavior against the supplied examples. Tests run in a separate environment with limited access; exact amounts, identifiers, and page results are checked by code rather than accepted because a model says the patch works.

What people approve

The engineering owner approves the code scope, test access, expected behavior, and proposed patch. Reviewers confirm behavior for missing data, permissions, error responses, and other consumers before merging. Instructions found in API documents or source comments are treated as content, not permission to execute arbitrary commands. The workflow does not deploy updates or use live customer credentials.

What we’d need to start

  • Old and new API instructions, version dates, change notes, and representative responses
  • The agreed integration files and their existing tests, with secrets removed
  • An authorized test service or supplied sample responses, expected behavior, and an engineering reviewer

How we’d test it

Use known examples of renamed fields, nested values, missing amounts, changed page markers, and incompatible error responses. Verify that the review finds all agreed consumers and that proposed tests fail on the old behavior where expected. Confirm currency and unit preservation, no missing or duplicate records across pages, and no silent zero for an absent amount. Measure review effort and missed changes against the current manual process.

Prepared for Technology & software. We would agree on the work after reviewing your brief, materials, and requirements.
