Using the Rest API

In this article, we will be using Curl to demonstrate the usage of the Rest API. You can use any preferred programming language or any tools as you like.
You may also want to directly interact with our online API using Swagger UI.
1. Generate a token
Once you have the userid and secret key, the first API need to be called is:
/gspLive_backend/user/generateToken
This API will return a temporary token that needs to be used in the API call thereafter.
SQLFlow Cloud Server
curl -X POST "https://api.gudusoft.com/gspLive_backend/user/generateToken" -H  "Request-Origion:testClientDemo" -H  "accept:application/json;charset=utf-8" -H  "Content-Type:application/x-www-form-urlencoded;charset=UTF-8" -d "secretKey=YOUR SECRET KEY" -d "userId=YOUR USER ID HERE"
SQLFlow on-premise version
TOKEN is not needed in the on-premise version. So there is no need to generate any token.
2. Generate the data lineage
Call this API by sending the SQL query and get the result includes the data lineage.
/gspLive_backend/sqlflow/generation/sqlflow
SQLFlow Cloud Server
curl -X POST "https://api.gudusoft.com/gspLive_backend/sqlflow/generation/sqlflow?showRelationType=fdd" -H  "Request-Origion:testClientDemo" -H  "accept:application/json;charset=utf-8" -H  "Content-Type:multipart/form-data" -F "sqlfile=" -F "dbvendor=dbvoracle" -F "ignoreRecordSet=false" -F "simpleOutput=false" -F "sqltext=CREATE VIEW vsal  as select * from emp" -F "userId=YOUR USER ID HERE"  -F "token=YOUR TOKEN HERE"
SQLFlow on-premise version
curl -X POST "http://127.0.0.1:8081/gspLive_backend/sqlflow/generation/sqlflow?showRelationType=fdd"    -H  "Request-Origion:testClientDemo" -H  "accept:application/json;charset=utf-8" -H  "Content-Type:multipart/form-data" -F "sqlfile=" -F "dbvendor=dbvoracle" -F "ignoreRecordSet=false" -F "simpleOutput=false" -F "sqltext=CREATE VIEW vsal  as select * from emp" -F "userId=gudu|0123456789" 
3. Export the data lineage in csv format
Call this API by sending the SQL file and get the csv result includes the data lineage.
/gspLive_backend/sqlflow/generation/sqlflow/exportFullLineageAsCsv
curl -X POST "https://api.gudusoft.com/gspLive_backend/sqlflow/generation/sqlflow/exportFullLineageAsCsv" -H  "accept:application/json;charset=utf-8" -H  "Content-Type:multipart/form-data" -F "userId=YOUR USER ID HERE" -F "token=YOUR TOKEN HERE" -F "dbvendor=dbvoracle" -F "sqlfile=@YOUR UPLOAD FILE PATH HERE" --output YOUR DOWNLOAD FILE PATH HERE
Sample:
curl -X POST "https://api.gudusoft.com/gspLive_backend/sqlflow/generation/sqlflow/exportLineageAsCsv" -H  "accept:application/json;charset=utf-8" -H  "Content-Type:multipart/form-data" -F "userId=auth0|5fc8e95991a780006f180d4d" -F "token=YOUR TOKEN HERE" -F "dbvendor=dbvoracle" -F "sqlfile=@c:\prg\tmp\demo.sql" --output c:\prg\tmp\demo.csv
Note:
-H "Content-Type:multipart/form-data" is required.
Add @ before the upload file path
--output is required.
Optional, if you just want to fetch table to table relations, please add -F "tableToTable=true"
4. Submit multiple SQL files and get the data lineage in CSV, JSON, graphml format.
The following Apis can take multiple SQL files as the input of analysis. Compress your SQL files into one zip file and upload the archive zip file as request body if you wish to submit multiple SQL files.
/sqlflow/exportFullLineageAsCsv

Troubleshooting
Under windows, you may need to add option --ssl-no-revoke to avoid some security issues, curl --ssl-no-revoke
