Abstract

A first application programming interface (API) with a first schema may be adapted to work with a second API with a second schema using mappings of schema properties and a directed graph. An API call specification of the first API may receive first API schema properties as input and provide first API schema properties as outputs. The first API schema properties may be mapped to corresponding second API schema properties, such as using semantic representations of the schema properties. An implementation of an API call for the first API may be created by using the schema mappings and selecting a path from a directed graph corresponding to the second API, where the path includes a node corresponding to an API call of the second API. Computer code may be generated using nodes of the path, and the computer code may be stored for later use.

Claims18

Dependent claims

A computer-implemented method, comprising:

obtaining a directed graph corresponding to an external API;
selecting a first internal API call specification for a first internal API call of an internal API, wherein the first internal API call specification comprises:
receiving a first value corresponding to a first internal schema property as input, and
providing a second value corresponding to a second internal schema property as output;
creating a first internal API call implementation by:
mapping the first internal schema property to a first external schema property,
mapping the second internal schema property to a second external schema property,
selecting a path from the directed graph for implementing the first internal API call, wherein a node on the path corresponds to a first external API call of the external API, wherein selecting the path comprises computing a cost for the path, and wherein the cost is computed using a number of external API calls on the path, and
generating computer code corresponding to actions of nodes of the path, wherein the computer code performs the first external API call of the external API;
and
storing the computer code.

A system, comprising at least one computing device comprising at least one processor and at least one memory, the at least one computing device configured to:

obtain a directed graph corresponding to an external API;
select a first internal API call specification for a first internal API call of an internal API, wherein the first internal API call specification comprises:
receiving a first value corresponding to a first internal schema property as input, and
providing a second value corresponding to a second internal schema property as output;
create a first internal API call implementation by:
mapping the first internal schema property to a first external schema property,
mapping the second internal schema property to a second external schema property,

One or more non-transitory, computer-readable media comprising computer-executable instructions that, when executed, cause at least one processor to perform actions comprising:

obtaining a directed graph corresponding to an external API;
selecting a first internal API call specification for a first internal API call of an internal API, wherein the first internal API call specification comprises:
receiving a first value corresponding to a first internal schema property as input, and
providing a second value corresponding to a second internal schema property as output;
creating a first internal API call implementation by:
mapping the first internal schema property to a first external schema property,
mapping the second internal schema property to a second external schema property,
selecting a path from the directed graph for implementing the first internal API call, wherein a node on the path corresponds to a first external API call of the external API, wherein selecting the path comprises computing a cost for the path, and wherein the cost is computed using a number of external API calls on the path, and
generating computer code corresponding to actions of nodes of the path, wherein the computer code performs the first external API call of the external API;
