1. Python and REST
Kevin Hibma

2. [NEW] ArcGIS Python API
New API that makes interacting with Esri RESTful technologies easy
Going into beta, released with ArcGIS 10.5
Scripting and Automation
iPython Notebooks
View webmaps, visualize results
Not an arcpy replacement.

3. [NEW] ArcGIS Python API
>> conda install –c esri arcgis >> python (optionally) >> conda install jupyter from arcgis.gis import * gis = GIS(“ “xxxx”, “xxxx”) gis.groups.list() gis.content.search(“Chiptole”)

4. What is REST? Why REST?
REST stands for Representational State Transfer. (It is sometimes spelled "ReST".) It relies on a stateless, client-server, cacheable communications protocol -- and in virtually all cases, the HTTP protocol is used. REST is an architecture style for designing networked applications.

Ummm what? (search has a lot of similar definitions)
For this session we’ll use the term REST to loosely describe how we (python scripts) connect and talk to a server / web service end point.
Why? Because its easier than SOAP! (another way to talk across the internet)

5. What can I do? ArcGIS Server ArcGIS Online (arcgis.com)
Consume, create, update, administer
ArcGIS Online (arcgis.com)
Consume, create, update, configure
Web services (both ArcGIS and not-ArcGIS)
Consume, update (with permission)

6. Development pattern
(optionally) Authenticate (get a token) depending on operation
Build URLs to hit different end points
Most requests are POST (vs. GET)
Send and receive a JSON payload
A REST service could send data back in another format

7. Time for some code

8. What to put where? Read API help doc Use Fiddler
(how do I know what a request needs and what a response gives)
Read API help doc
Use Fiddler
With fiddler running, perform actions
in a browser or other client inspect
requests / response
WebBrowsers have built in consoles
to watch requests
URL
Query
parameters
Response

9. Links Documentation and examples
Ready to go tools, scripts and command line
Code as iPython notebook
