Create a complex IVR/Survey via API¶

First create a survey template via API, this is similar to creating the survey template on the webUI at http://HOSTNAME_IP/module/survey/add/

CURL Usage:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"name": "Complex Survey created from API", "user": "/rest-api/users/1/"}' http://HOSTNAME_IP/rest-api/survey-template/

Result:

{
    "url": "http://HOSTNAME_IP/rest-api/survey-template/29/",
    "name": "Complex Survey created from API",
    "description":null,
    "created_date": "2021-06-19T20:34:47.283180+02:00",
    "updated_date": "2021-06-19T20:34:47.283199+02:00",
    "user": "http://HOSTNAME_IP/rest-api/users/1/"
}

You should get a result similar to the example note the Survey-Template-ID from the result url data. (eg. “url”: “http://HOSTNAME_IP/rest-api/survey-template/29/”, the ID is 29)

Note the survey-template-ID,it will be used when you create the sections and the branching.

1) Create a Section into your Survey Template¶

So far, you have created a Survey Template. At the moment it’s empty, as you can see on the UI.

The documentation for different types of section is at, Survey & IVR Configuration

We will create as an example: * a) Multi-choice (section type 2) to offer 2 options with some branching * b) Play message (section type 1) with simple message * c) API (section type 11) which will send an API request.

Here is a list of section types for reference:

PLAY_MESSAGE = 1
MULTI_CHOICE = 2
RATING_SECTION = 3
CAPTURE_DIGITS = 4
RECORD_MSG = 5
CALL_TRANSFER = 6
HANGUP_SECTION = 7
CONFERENCE = 8
DNC = 9
SMS = 10
API = 11
QUEUE = 12
ASR = 13
API_ASYNC = 14

To create any section via the API, you will need the survey-template-ID from before (which was 29).

All the API calls will return a result which will contain the section-template ID, eg:

{"url":"http://HOSTNAME_IP/rest-api/section-template/75/", ...

First, create a Multi-Choice Section-Template, as follows:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"type": "2", "audiofile": "/rest-api/audio-files/18/", "question": "Multi-choice, select 1 or 2", "survey": "/rest-api/survey-template/29/", "retries": 3, "timeout": 5, "key_1": "1 Pressed", "key_2": "2 Pressed", "order": 1, "queue": null}' http://HOSTNAME_IP/rest-api/section-template/

There are a lot of parameters available, we advise you to inspect them via the API explorer: http://HOSTNAME_IP/rest-api/section-template/

Note here are the retries & timeout were used, along with key_1 & key_2 as we want to capture contacts pressing 1 or 2.

Let’s assume that in the API result the section-template ID was 75.

Now create a Play message Section-Template, as follows:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"type": "1", "audiofile": "/rest-api/audio-files/20/", "question": "Simple Message", "survey": "/rest-api/survey-template/29/", "order": 2, "queue": null}' http://HOSTNAME_IP/rest-api/section-template/

Assume that in the API result the section-template ID was 76.

Now, let’s create an API Section-Template, as follows:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"type": "11", "audiofile": null, "script": ".", "question": "API HTTP Get Request", "survey": "/rest-api/survey-template/29/", "completed": true, "api_url": "http://mydomain.com/CustomAPI", "order": 3, "queue": null}' http://HOSTNAME_IP/rest-api/section-template/

Note: We have used completed to mark a call as completed when reaching this section, this is not mandatory.

Assume that in the API result the section-template ID was 77.

2) Create Branching into your Survey Template¶

Branching is used on the multi-choice to tell the IVR which section to go to when pressing a certain key.

Create 2 branchings for press-1 & press-2.

When pressing 1, we want to go to the Play Message (so it will go from section-template ID 75 to 76)

Create the branching via API, as follow:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"keys": "1", "section": "/rest-api/section-template/75/", "goto": "/rest-api/section-template/76/"}' http://HOSTNAME_IP/rest-api/branching-template/

When pressing 2, we want to go to the API section (so it will go from section-template ID 75 to 77).

Create the branching via API, as follow:

curl -u username:password --dump-header - -H "Content-Type:application/json" -X POST --data '{"keys": "2", "section": "/rest-api/section-template/75/", "goto": "/rest-api/section-template/77/"}' http://HOSTNAME_IP/rest-api/branching-template/

3) Closing remark¶

You can now use this complex IVR with a campaign, remember that a campaign when it is started will create a copy of that IVR/Survey, so if you modify a survey after a campaign is started, you will need to recreate your campaign from the beginning for the changes to take effect.
