# Overview
## API Introduction
***
Communication between software and external applications is defined by an application program interface (API). Logic ERP Solutions require APIs to allow other applications to create,upload and get data from Logic ERP Solutions.
An Application Programming Interface (API) acts as a data broker between an Enterprise Resource Planning (ERP) system and an application requesting data. The API receives the request, as long as it has the appropriate permissions, and provides the requested data to the application. Furthermore, APIs govern the types of data that may be requested and the manner in which the data is delivered. APIs have been a part of ERP systems for a long time, and regardless of the type of computing hardware used, they enable the transfer of data between programs. The API can be used in a variety of situations, such as transferring data from a other server to Logic ERP Solutions, Create data through the APIs and it can also help in fetching the details from the Logic ERP Solutions.
Logic software offers a range of API integration options, allowing for a flexible and customizable system to meet a variety of integration requirements. These include :\
PUSH : which enables external systems to automatically push the information into Logic when an event occurs, such as saving a sale bill.\
PULL : which allows for the collection of information from external systems at a predetermined time frequency, such as obtaining a sale bill.
As Example Below :
**Authorization Table Description**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/api-documentation/overview.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
