API integrations are scoped by evaluating endpoints, payload schemas, authentication protocols, and third-party rate limits against your functional requirements.
The Technology department conducts an audit of your technical documentation to determine build architecture, testing overhead, and error-handling requirements before issuing a bespoke quote.
What you must supply
To scope an API integration accurately, the Technology department requires complete technical details for every system involved. Partial briefs result in deferred scoping or architectural assumptions that introduce delivery risk.
You must provide:
- Official documentation, OpenAPI specifications, or Postman collections for both the source and target platforms.
- Functional staging or sandbox environment credentials populated with representative test records.
- Authentication specifications, including OAuth 2.0 flows, long-lived bearer tokens, webhook signing secrets, or mutual TLS requirements.
- Field-level data mappings detailing how attributes in the source system translate to the destination schema, noting mandatory versus optional fields.
- Transaction volumes, data payload sizes, and frequency requirements (such as real-time event-driven webhooks versus scheduled batch synchronisation).
- Expected error behaviours and retry requirements for each connected service.
The scoping workflow
Scoping follows a direct sequence between your team and our studio departments:
1. Receipt and intake: Operations & Client Services logs your brief via the portal. Our first reply target is within 24 hours to confirm receipt and verify that all necessary technical assets have been supplied. 2. Documentation and schema review: A technical lead in the Technology department reviews the third-party endpoints, pagination structures, payload schemas, and API rate ceilings. 3. Failure mode analysis: We define handling procedures for downstream outages, HTTP 429 rate limit responses, token expirations, and malformed payload validation errors. 4. Architecture and middleware specification: We determine whether the build requires serverless functions, permanent webhook listeners, database queues, or caching layers to maintain reliability. 5. Commercial and technical quotation: We issue a formal technical specification and bespoke quote within 48 hours of receiving a complete brief with working sandbox credentials. Any standard package work is priced directly on the packages page.
Timings and commercial terms
Xylora Studios operates Monday to Thursday, 09:00 to 17:00 GMT. Technical assessments, scoping audits, and quote deliveries take place exclusively during these working hours. Briefs received late on Thursday or over the weekend enter the technical review queue on Monday morning.
- Quote delivery: Bespoke quotes are delivered within 48 hours of receiving a complete brief containing all required credentials and schemas.
- Referral terms: If you were introduced to Xylora Studios by an existing client or partner, you typically receive 10-30% off your project cost, confirmed in writing directly on your quote. The referring partner earns commission through our ambassador programme.
- Deposits are non-refundable once your production slot is held. Before work begins, sums not yet earned are refunded pro rata; after work begins, completed work and booked time are charged. Defects are fixed free of charge within the acceptance window. The full terms are on the Refund Policy page of the main site.
Failure points and scoping blockers
Scoping slows down or halts when technical platform realities conflict with general project assumptions. Common blockers include:
- Missing sandbox environments: If an external platform lacks a dedicated testing tier, we must architect safe mocking strategies to prevent testing against live production records, which increases scoping complexity.
- Undocumented rate limits: External services that throttle requests aggressively require custom queueing and exponential backoff mechanisms. If rate limits are unknown, performance guarantees cannot be established.
- Dynamic or loose schemas: Platforms that permit unvalidated custom fields require defensive validation logic to catch malformed payloads before transmission.
- Restricted administrative privileges: Missing permissions for generating developer API keys or configuring webhook callback URLs prevent our team from verifying endpoint behaviour during scoping.
Scoping readiness checklist
Before submitting your integration request through the Ask Xylo chat on this portal, confirm you have completed the following:
- [ ] Confirmed API access is enabled on your tier for all third-party platforms.
- [ ] Gathered official technical documentation or schema files for each service.
- [ ] Generated functional sandbox or staging API keys with appropriate scopes.
- [ ] Drafted a field-mapping matrix covering required, optional, and transformed data fields.
- [ ] Defined your data timing model (real-time webhook alerts versus scheduled batch runs).
- [ ] Identified a technical contact on your side who can clarify third-party account settings.
