eSIM API
Build the whole connection.
Bring connectivity into your application through one service model. Connect the catalog to an authorized purchase, follow fulfillment and installation, then help customers manage the service they bought. Keep your customer experience in control of the journey.
An integration you can follow
EXAMPLEBIRD · CONNECTIVITY
One service. Connected records.
Discover and select
Read coverage, terms, price and eligibility.
Purchase and fulfill
Follow one accepted order to its outcome.
Install and use
Resolve private setup and observe first use.
Illustrative integration flow. Follow the current API contract for supported operations and recovery behavior.
Start with the contract
Model the service your customer is buying.
A profile identifies the eSIM, a package describes an allowance and an order records the purchase. A recurring subscription adds billing periods and continuing service. Connect those identities in your application without collapsing their different states.
Read before you write
Discover the offers and effective capabilities for the intended customer. Use published pricing and current eligibility rather than keeping a separate hardcoded catalog in the app.
Keep the accepted intent
Preserve the selected offer and request identity through the purchase. Follow the existing order after an uncertain response, so recovery does not become an accidental second charge.
Build a complete journey
Connect purchase to a working device.
Track the order through financial acceptance and provisioning, then provide a private installation path. Report the actual outcome at each boundary instead of labeling the customer connected when checkout finishes.
Keep credentials private
Resolve installation credentials through the authorized customer experience. Exclude them from telemetry, public Markdown, issue reports and general support messages.
React to observed state
Use the supported events and reads for the service. Retain observation times, handle missing information explicitly and let your interface resume from the state it actually receives.
Operate the integration
Make recovery part of the implementation.
Test a controlled purchase, installation and first use, then an interrupted or refused operation. Use the same service identities to connect support, financial records and lifecycle changes.
Work with your coding agent
Give the agent the current API description and the relevant task guide. Ask it to map supported operations, implement the authorized flow and show evidence for the completed customer outcome.
Carry acquisition through the journey
Keep campaign identifiers with the acquisition and customer handoff. Join them to the recorded business conversion in your application; passing a query parameter is only one part of attribution.
eSIM API questions
Is an eSIM API only an installation-code endpoint?
Can a coding agent build the integration?
How should we handle an uncertain purchase response?
What belongs in conversion measurement?

Put it into practice.

Map the supported catalog, purchase and installation operations to your application. Rehearse recovery with the same order before expanding the integration.
