A2P Messaging

A2P is the acronym for “Application to person”, and it refers to the sending of SMS to real people through a SMS delivering platform or by an SMS-API.

This usually covers bulk SMS delivery or the use of automations, instead of disclosing information by the phone with the company’s customer service staff.

API integration

Integration refers to creating a connection between a system and any API.

A business can integrate an API to perform tasks such as data sharing, the embedding of data, syncing data from several aggregators, among others. With the general goal of enhancing productivity through automatic processes.

To integrate the Octopush SMS-API please refer to our documentation.


At its origin, the term API is the acronym for Application Programming Interface. It refers to a set of subroutine definitions, protocols, and tools that developers use to make applications to communicate between each other.

Nonetheless, current uses for the term API refers to productized software designed for the consumption of specific audiences.

SMS APIs, as software products, are standardized (typically HTTP and REST) sets of code that allow developers to manage an SMS delivery service by integrating it into a different software or application.

AR Status

Frequently abbreviated as AR (for acknowledgement of receipt), is the confirmation that a ticket or payment has been received. The proof of delivery lies in this information or AR, which the recipient files to the sender to confirm the reception.

In SMS, it is possible to receive a notification, which is valid as an acknowledgement of receipt, once the recipient has received the SMS message.

With the Octopush SMS API an AR can be delivered via webhook.


Blacklisting takes place when a group or authority creates a list of individuals, countries or entities which they consider distrustful or unacceptable.

In mobile communications, the user can blacklist the reception of promotional SMS by replying with a specific short code (usually referred as the STOP mention). The SMS service won’t be able to deliver messages to any blacklisted numbers.

Bulk SMS

Delivering SMS in bulk means using a SMS platform to send the same text message (or a similar text message personalised with tags) to the totality, or a selected portion, of a business’ contact list at the same time.

This can take place for promotional or transactional purposes.

A callback is an executable in computer programming, sometimes called a post treatment function. A callback passes an argument from one code to another. Once this last code receives the argument, it is expected to call back (execute) the given argument at a given time.

Callbacks can be synchronous, when the execution of the argument is immediate; or asynchronous, when the execution of the argument happens at a later point in time.

For the Octopush API SMS, it is possible to register a callback URL to execute certain actions. Those callbacks are made by HTTP POST request.

Octopush SMS API uses callbacks to achieve the full integration of its services. Learn how to implement them here.

Not sure of how to generate leads with a CTA in a message text?


n digital marketing, click through rate (abbreviated CTR) is a metric that helps businesses to measure the performance of their marketing campaigns. It consists in the ratio at which a certain URL address is clicked, an email or SMS is seen, to the number of users who watched the marketing material.

The formula goes as follows:

(Total Clicks) / (Total Impressions) = Click-Through Rate

CTR often is calculated for Ads, but it also helps measure engagement in content, whether the user clicks on an anchor text, image or CTA.

A high CTR could mean the users are the most likely interacting with the content, thus the campaigns are successful. However, it is important to convey it with other statistics, as the CTR does not care for other factors such as customer satisfaction or sales.

Landing Page

Landing pages are websites designed with the single goal of pushing visitors down the purchasing funnel.

Visitors usually don’t arrive organically (from web browsers) to this page, instead they do it from an external cue such as an email, advertisement, or social media.

Their range of use comes from acquiring more leads to a specific promotion. They can belong to the main website or they can be specific microsites created outside the main domain.

Long SMS

Under a GSM-7 encoding, the maximum length of a SMS message is 160 characters. This number can drop dramatically to mere 70 characters maximum length when using special characters, non-Latin alphabets, or Latin accented characters.

However, to overcome such limitations, it is possible to implement long SMS.

Long SMS is a concatenation of several SMS messages, that the receiving mobile device recombines to display a single lengthier message.

Each composed SMS message is billed separately, and holds a maximum size of 153 characters instead of 160. Once it is recombined, the receiver handset sees a single long message.

Long SMS have a maximum length of 764 characters in non-Unicode.

Using special characters can reduce to 63 each fragment, in this case long SMS can reach a maximum length of 504 characters.

Long SMS is a feature Octopush offers on its Premium version.

Open Rate

In marketing, open rate is a performance tracking metric that indicates how many people open or view an email or an SMS.

It is commonly expressed as a percentage. That percentage comes from dividing the number of messages opened by the number of messages sent.

In order to obtain a trustful open rate, the recipient must effectively view the message (it’s not enough reading the text through the push notification preview) and/or interact with it.

Learn about the fantastic 98% open rate for SMS here.

Opt-in lead

In sales, a lead is a potential customer that has not transitioned to purchasing.
