This page contains a step-by-step tutorial on how to retrieve OAuth Bearer token, create a Player, retrieve available Avatar creation parameters, create an avatar from a photo and download its model files along with extra Avatar meta-information using the curl command line utility.
To obtain curl utility for Windows, please visit the following page: https://curl.haxx.se/windows/. Please consult your Linux/macOS distributive packaging system help to install curl utility.
Please note that code samples syntax is different for Windows and for Linux/macOS platforms, thus see the corresponding sample section for your platform by clicking on the platform title.
Go to https://accounts.avatarsdk.com/developer/ (create an application if you have no application yet), copy App Client ID and App Client Secret from Client Access application to the corresponding variables. Please make sure you have set Authorization Grant to Client credentials. Set the TOKEN variable to the access_token value after successful authorization. Please note, that token will expire in 36000 seconds and you will need to run authorization procedure again.

SET "CLIENT_SECRET=S8TM5..." curl -X POST --user "%CLIENT_ID%:%CLIENT_SECRET%" ^ "https://api.avatarsdk.com/o/token/" ^ -F "grant_type=client_credentials" { "access_token": "PAvD64lbikgVA0GzxgKV2ZhLnPbZ8P", "token_type": "Bearer", "expires_in": 36000, "scope": "read write" } SET "TOKEN=PAvD64lbikgVA0GzxgKV2ZhLnPbZ8P"

Query all available parameters for base/mobile subtype of head_1.2 pipeline. Please note, that this request is useful during parameters discovery and should be omitted during normal application workflow once you figure out which parameters fit you best.

Query all available enumerable export parameters for the base/mobile subtype of the head_1.2 pipeline. Please note, that this request is useful during parameters discovery and should be omitted during regular application workflow once you figure out which parameters fit you best.
curl -H "Authorization: Bearer %TOKEN%" ^ -X GET ^ "https://api.avatarsdk.com/export_parameters/available/head_1.2/?pipeline_subtype=base/mobile" { "blendshapes": [ "mobile_51" ] }
curl -H "Authorization: Bearer $TOKEN" \ -X GET \ "https://api.avatarsdk.com/export_parameters/available/head_1.2/?pipeline_subtype=base/mobile" { "blendshapes": [ "mobile_51" ] }
We will use the following parameters for our avatar:
{ "model_info": { "plus": [ "gender", "age", "race" ] }, "avatar_modifications": { "plus": { "curved_bottom": true } } }
And the following export parameters:
{ "format": "glb", "embed": true, "additional_textures": [ "lips_mask" ], "embed_textures": true, "blendshapes": { "list": [ "mobile_51" ] } }
Please note: since we are using Exports API, blendshapes should be specified in export parameters.
Save avatar parameters and export parameters into the files parameters.json and export_parameters.json correspondingly. Run the avatar computation request with the parameters files above, the photo.jpg image from the current directory (adjust path if necessary), TOKEN and PLAYER values obtained earlier and save the avatar code for further use:
