API Integration Consulting: Business Apps That Pass Data Without Re-Keying
An order lands in the store and someone types it into accounting. A form comes in and someone copies it to the CRM. Each handoff costs a few minutes, and every copy is a chance for a typo that surfaces weeks later.
API integration consulting is the design and build of connections that move records between your business applications automatically: a new customer in the CRM appears in accounting, a paid order creates an invoice, a web form becomes a lead. Lightray Solutions builds these on Microsoft's integration tools, and Edward Pinela, MBA, does the work himself.
An API, short for application programming interface, is the documented way one application lets another read or write its data, and most cloud apps publish one. The consulting part is deciding what should sync, in which direction, which system owns each field, and what happens when a call fails.
Integrations are quoted per connection in a written, itemized scope after a free 30-minute strategy call, requested through the form or by phone. Moving data into a warehouse for reporting is a different job, covered under cloud data integration services.

Which applications usually need connecting?
The ones where people re-key data today. Typical pairs are CRM and accounting for customers and invoices, e-commerce and accounting for orders and payments, web forms and the CRM for leads, and CRM and email marketing for contacts and consent. Each pair needs a decision about which system is the source of truth.
Two-way sync sounds appealing and causes most integration headaches, because two systems editing the same field eventually disagree. A sound design gives each field one owner: the CRM owns the contact, accounting owns the invoice and its payment status, and the other side only reads them.
Which tools fit which integration?
Four Microsoft options cover most needs. Power Automate suits business-owned flows using its prebuilt connectors. A custom connector wraps any REST API so Power Automate, Power Apps or Logic Apps can call it. Azure Logic Apps suits higher-volume, IT-owned workflows. Azure Functions runs small pieces of code where logic is too complex for a designer.
Microsoft says Logic Apps, Power Automate, Power Apps and Copilot Studio share more than 1,000 prebuilt connectors, and that a custom connector is a wrapper around a REST API, described by an OpenAPI definition or a Postman collection. Webhooks, where an application calls a URL the moment something happens, replace polling when the source supports them; an HTTP-triggered Logic App or Function receives the call.
Power Automate's own design and licensing questions are covered on Power Automate consultants; the table compares the choices by integration need.
| Integration need | Typical approach | What to watch |
|---|---|---|
| A web form submission creates a CRM lead | Power Automate flow with the form and CRM connectors, or the CRM's own form tool | Duplicate leads; consent fields mapped exactly |
| A paid online order creates an invoice in accounting | Webhook from the store to a Logic App or flow | Refunds, partial payments and tax lines; retries creating double invoices |
| CRM customers kept in step with accounting | Scheduled flow or Logic App with a field-ownership map | Two systems editing the same field; matching on a stable ID, not a name |
| An app with an API but no prebuilt connector | Custom connector built from an OpenAPI definition | Authentication type; API changes that need the connector republished |
| Complex transformation or high volume | Azure Function called from a Logic App | Who owns and deploys the code after handover; Azure usage billed by Microsoft |
| Nightly bulk transfer between systems | Scheduled Logic App or flow with pagination | Request limits; runs that time out partway through |
How are API integrations kept secure?
By authenticating the way each API intends, usually OAuth 2.0, which grants a scoped token instead of sharing a password, and by keeping every secret out of the flow itself. API keys and client secrets live in Azure Key Vault, and connections run under service accounts rather than a person's login.
Microsoft documents Key Vault references for Azure Functions and Logic Apps (Standard): the app setting points at the secret, the app reads it through its managed identity, and a rotated secret is picked up within 24 hours without code changes. Each integration also gets the narrowest permissions the API offers, read-only wherever it only needs to read.
What happens when an API call fails or hits a limit?
It retries, then tells someone. Azure Logic Apps by default retries a failed call that returns a timeout, a 429 'too many requests' or a server error up to four times at growing intervals. If it still fails, a catch step sends the failed record and the error to whoever owns the integration, so nothing disappears quietly.
Retries need care. A call that created an invoice but timed out before replying can create a second invoice when retried, so every write checks for an existing record first. Limits apply on both sides: the other application's API quota, and Microsoft's own, such as the official limit of 40,000 Power Platform requests per 24 hours for a Power Automate Premium user in Microsoft's request limits. Retries count against those limits too.
Run history is reviewed on a schedule, and Logic Apps can send run data to Azure Monitor, which raises an alert when failures climb.
Who owns the integrations after handover, and what does it cost?
You do. Every flow, Logic App and Function lives in your Microsoft tenant and Azure subscription, documented with a diagram, a field map, the secrets it uses and who gets alerts. A handover session walks your administrator through changing a mapping and reading a failed run, so the integration doesn't depend on Lightray.
Each integration is quoted in a written, itemized scope after the free call. Azure usage for Logic Apps runs, Functions and Key Vault operations is billed by Microsoft separately, and any premium Power Automate licensing is listed in the scope before work starts. Delivery is remote, by video and screen share. Wider Azure work sits under Azure consulting, and governance across the Power Platform under Power Platform consulting.
Edward brings 20+ years of experience and 200+ projects, and Lightray's standing is a 4.9 Google rating with an A+ at the BBB.

Frequently asked questions
Can't we use the integration built into our apps?
Often, yes, and it should be checked first. Many CRMs and accounting systems ship native integrations with each other. Custom work makes sense when the native option doesn't map the fields you need, doesn't handle your edge cases, or doesn't exist.
How much does an integration cost?
It is quoted per integration in a written scope after a free call, because the price depends on the APIs involved, the number of fields and how much error handling the process needs. Azure and premium connector costs are listed separately so the running cost is clear.
How long does it take to build one?
The scope gives a timeline. One-way flows between apps with prebuilt connectors are the quickest; custom connectors, two-way sync or apps with thinly documented APIs take longer, mostly in testing.
Is the work done remotely?
Yes. Design sessions run over video, and the build happens in your tenant and Azure subscription with credentials your administrator issues. Nothing requires a visit, and test runs are shown live on screen share.
What do you need from us?
Admin or API access to each application, a sandbox account where one exists, examples of the records that should move, the rules for edge cases such as refunds or duplicates, and a named person who will receive failure alerts.
