Postscript 1.1
Postscript is an SMS marketing software for growing Shopify stores.
OverviewCopy
The Postscript connector allows you to list keywords that you can use to add subscribers to your Shopify store. Unlock a new marketing channel guaranteed to drive revenue, not just clicks.
AuthenticationCopy
When using the Postscript connector, the first thing you will need to do is go to your Tray.io account page, and select your workflow. Once in the workflow dashboard itself, select and drag the Postscript connector from the connectors panel (on the left hand side) onto your workflow.
With the new Postscript connector step highlighted, in the properties panel on the right, click on 'New Authentication' under the 'Settings' heading.
As you can see from the image below, in order to complete authentication set up, Tray.io requires that you input your 'API Key'.
To find your API Key, click on the cog on your Postscript Dashboard page.
Your API key is in the Settings section.
Copy and paste the API Key from your Postscript Account page into the API Key field in the above Tray.io authentication dialog. Once you have added the authentication, it will already be selected in the authentication section in the Tray.io properties panel.
You have now completed the authentication process and can use the Postscript connector. Your auth field will now automatically select the Postscript authentication created until stipulated otherwise.
Available OperationsCopy
The examples below show one or two of the available connector operations in use.
Please see the Full Operations Reference at the end of this page for details on all available operations for this connector.
Example usageCopy
TRAY POTENTIAL: Tray.io is extremely flexible. By design there is no fixed way of working with it - you can pull whatever data you need from other services and work with it using our core and helper connectors. This demo which follows shows only one possible way of working with Tray.io and the Postscript connector. Once you've finished working through this example please see our Introduction to working with data and jsonpaths page and Data Guide for more details.
Below is a brief example which demonstrates how to iterate through the keywords stored within your Postscript app.
This example imagines a scenario whereby the first step is manually triggered. This in turn kicks off the Tray workflow and will get the keywords in the Postscript account one by one.
The outlined is as follows:
Set up your manual trigger and first Postscript connector step.
Add a Loop connector to iterate through your keywords.
Add a step to add subscriber to each keyword individually.
1 - Setup trigger & List available keywordsCopy
Once you have clicked 'Create new workflow' on your main Tray.io dashboard (and named said new workflow), select the Manual trigger from the trigger options available:
Once you have been redirected to the Tray.io workflow dashboard, from the connectors panel on the left, add a Postscript connector to your second step. Set the operation to 'List available keywords'.
Feel free to re-name your steps as you go along to make things clearer for yourself and other users.
Now when this workflow is run, it will pull down a list of keywords from the Postscript API. This means you will be able to view them when you click through your debug panel, and expend the output field.
2 - Add a Loop stepCopy
Next, we add a Loop connector to the workflow and set the operation to 'Loop list'.
Use the connector-snake to generate the jsonpath you will need, by clicking and dragging on the orange circle mapping icon, left of the 'List' field name.
JSONPATHS: For more information on what jsonpaths are and how to use jsonpaths with Tray, please see our pages on Basic data concepts and Mapping data between steps
CONNECTOR-SNAKE: The simplest and easiest way to generate your jsonpaths is to use our feature called the Connector-snake. Please see the main page for more details.
Once you have dragged it over to your first Postscript step, you will see a dropdown list of options appear. Select the keywords array. Your output should be similar to: $.steps.postscript-1.keywords.
This will enable us to iterate over the list of keywords, and perform operations for each one, during each loop cycle.
3 - Add subscriber to keywordCopy
Finally, drag another Postscript connector step into the Loop Collection itself, and set the operation 'Add subscriber'.
In this example the 'Phone' has been hard coded, however this is just to demonstrate that it is possible. Best practices dictate that jsonpaths are used to automate the answer, incase they change at some point in the future.
Use the same connector-snake method for generating the jsonpath to get the 'keyword' field, only this time it will be taken from the loop step.
This will mean that a reply will automatically be sent based on the keywords previously found, per each loop iteration.
