To directly use the QR Code generation system in MailUp, you need to insert the generation link into the body of the email you are writing, either as an image or as a download link. There are different types of QR Codes on the market, both standard and proprietary. MailUp generates only QR Codes of the type QR Code Model 2, also known as the standard basic QR Code. The default version is 5.

The link to generate a QR Code would be the following (this is an example): https://pseapi.servicesmu.com/api/mup/oqrcode/idconsole/[_idoptin]/[_hash]?data=test.

Where:

• https://pseapi.servicesmu.com/api/mup/oqrcode and [_idoptin]/[hash] are fixed values,

• idconsole is the identifier of the current MailUp console, the number that identifies the MailUp account,

• ?data=test is the value that will be encoded and can be a fixed value or a dynamic field, as detailed below.

For example, if my MailUp account has the identifier 88993, the link to use will be: https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=test

How to Use a Fixed QR Code (Encoding the Same Value for All Email Recipients)

To send the same QR Code, which encodes the same value, to all contacts receiving an email, the data parameter in the link must contain a fixed value.

For example, if my MailUp account has the identifier 88993:

• The link https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=test will generate a QR Code that encodes the word "test".

• The link https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=000121428 will generate a QR Code that encodes the word "000121428".

Link	Coded value	Example of QR Code created
https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=test	test
https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=000121428	000121428

How to Use a Dynamic QR Code (Encoding a Different Value for Each Email Recipient)

To send a personalized QR Code to all contacts receiving an email, the data parameter in the link must be associated with a Dynamic Field. In this way, during the email sending process, MailUp will associate the link with the value of the dynamic field present in the recipient's profile.

For example, if my MailUp account has the identifier 88993 and a field named cod_cli is defined, which indicates the customer code (different for each recipient registered in MailUp):

The link https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=[cod_cli] will generate a different QR Code for each recipient who receives the email. The QR Code will encode the customer code associated with each recipient (which is saved in the cod_cli field).

Link	Recipient	Value of the Dynamic Field cod_cli	Coded value	Example of QR Code created
https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=[cod_cli]	email1@mailup.com	AF-123-666	AF-123-666
https://pseapi.servicesmu.com/api/mup/oqrcode/88993/[_idoptin]/[_hash]?data=[cod_cli]	email2@mailup.com	721mailup.com721	721mailup.com721

How to Insert the QR Code as an Image in an Email

To insert a QR Code (whether dynamic or static) into an email message using the Drag & Drop editor:

1. Add an image.

2. Make the image Dynamic.

3. In the Dynamic URL of the image, insert the QR Code generation link (whether it is the dynamic or static generation link).

This way, the image specified in the email will be linked to the QR Code generator, and when the recipient receives the email, the QR Code image will appear in the designated position.

Editor Drag&Drop	Received Email
First row consists of two images related to two dynamic QR Codes that encode the values of the dynamic fields cod_cli and cod_ltm. Second row consists of two images related to two static QR Codes that encode the values test and 000121428.

If the dynamic field to be encoded for a recipient does not contain any value and the QR Code is inserted in the email as an image, that recipient will receive an email with an empty image.

Editor Drag&Drop	Received Email
The first row consists of two images related to two dynamic QR Codes that encode the values of the dynamic fields cod_cli and cod_ltm. The second row consists of two images related to two static QR Codes that encode the values test and 000121428. For the recipient in question, the dynamic field cod_ltm is not populated. For the recipient in question, the dynamic field cod_cli is populated.

How to Enable the Download of a QR Code from an Email

To insert the QR Code as a download link (whether dynamic or static) using the Drag & Drop editor:

1. Add a link.

2. Insert the QR Code generation link as the URL (whether it is the dynamic or static generation link).

This way, the link in the email will be associated with the QR Code generator, and when the recipient clicks on the link, the QR Code image will be downloaded.
