Sending Messages to a Mobile Number

Tall Bob support two types of SMS messages Plain SMS and Campaign Based SMS.


Opt-Out Links

Both types of SMS messaging support the inclusion of Opt Out Links (sometimes referred to as Unsubscribe links) for Spam Compliance, they can be inserted into a message using the {OptOutURL} placeholder.


Personalised Messages

Tall Bob uses a subset of the Liquid Templating language so that you can personalise your plain SMS messages through the use of special tags in your messages to personalise messages double curly braces should be used for example “Hi {{ name }} thank you so much for attending our event last night” using personalisation does require that you include additional information in your API request and is only supported in the Send SMS To List of Mobiles endpoint.


Plain SMS Messages

Tall Bob offers two endpoints related to sending plain SMS messages


Link Shortening

You can also utilise our link-shortening service as a part of the Plain SMS API, it will allow you to take long URLs like https://tallbob.com/awesome-garden-gnomes-and-pink-flamingos and make them something nice and short like http://tallbob.me/O8WJ


Campaign-Based SMS Messages

Tall Bob also supports the sending of Campaigns Based SMS messages to one or more individual phone numbers, this allows you to send messages that include links to landing pages, which include different engagement tools such as:

  • Video Content

  • Scratch and Reveal

  • Spin the Wheel (Beta)

  • Surveys and Forms

  • etc

To send messages of this type you should refer to the Send SMS Campaign To List of Mobiles endpoint


Sending messages to Groups and Contacts

Tall Bob supports the sending of pre-built campaigns to Groups (sometimes referred to as Lists) and contacts that have been previously created in the platform, you can send Campaign messages by referencing:

  • The Group ID (this is a unique id assigned by the Tall Bob platform, to a group of contacts when the new Group is created)

  • A list of one or more Contact ids (these are unique ids assigned to a Contact by the Tall Bob platform at the time of Contact Creation)

  • A list of one or more External ids (External ids are unique identifiers created and managed by an external system such as your CRM to identify Contacts)

You can send messages to groups and contacts via the Send SMS Campaign endpoint, which will require that you specify an existing template_id from within the platform.

Note: As all content related to this campaign is pre-built and specified by the template id you supply when calling this endpoint, the use of personalisation, link shortening and the like are to all be defined within the Campaign Template.


Two Way Chat

Tall Bob offers a specialised endpoint that helps you manage Two Way Chat at scale without having to worry about the potential confusion of having multiple conversations between your business and clients ending up muddled up in the one conversation thread because they all come from a single long code. Some businesses that commonly utilise this sort of feature are:

  • Real Estate Agencies

  • Delivery Companies

  • Food Delivery Services

Messaging via the 2-way chat endpoint uses a 2-part key to manage the long code when sending messages, you will need to specify a reference in the payload you are sending along with the phone number the message is to be sent to. Tall Bob’s platform will then manage the assignment of the long code from a pool of dedicated long codes attached to your account, automatically managing the entire process for you.
