PowerApps Digital Signature to Sharepoint List

Hi there,

 

I noticed most of the digital signature questions here are outdated, so I would like to ask this here:

 

My scenario is I just need one digital signature (not a set of images) to be saved to a specific SharePoint record. My questions:

 

- What datatype in SharePoint should I use? Should it be a picture/hyperlink?

- How can I send the data from PowerApps to SharePoint for that record?

 

One of the processes I'm automating is that the users need to sign it off before submitting their records (do not worry about the SharePoint list being edited; there are workarounds we've planned for this). We just need this done and saved to a record.

 

Hoping someone can help me out, thanks!

An easy and multi-purpose solution is found to add pen-input to Sharepoint/Email/PDF by utilizing the addition of a PowerApps Json functionality added on 02/05/2019.

The Short description on how to make this work is to save the pen input image in a JSON format asking the JSON function to include Binary Data:

Set( PenVar, JSON( PenInput1.Image,JSONFormat.IncludeBinaryData ) );

Hi @david_castillo,

 

Do you want to save a Digital Signature into your SP list?

 

The user @msmith has faced same needs with you, please check the response within the following thread:

https://powerusers.microsoft.com/t5/General-Discussion/Save-Signature-to-SharePoint-List/td-p/76661

 

For your first question, if you want to save your Digital Signature into your SP list item, I afraid that there is no way to achieve your needs in PowerApps currently. 

 

The URL the Pen input control captured as below (same output result as the Add picture control😞

 

appres://blobmanager/899e173585554dfca6eb38b373599f3b/20

which could not saved within Picture/Hyperlink type column.

 

For your second question, currently, there is no way to save a digital signature (captured via the Pen Input control) into SP list item within PowerApps.

 

As an alternative solution, you could consider take a try to save your digital signature as image file into a SP library, and then within your SP list, add a column to store the link to the image file (digital signature) stored within your SP library.

 

Please check and see if the following blog would help in your scenario:

riggHi,

 

I have been playing with this for a couple of weeks now and it is super frustrating that there is not an out of the box solution to this. Why are pen inputs treated differently to images.

 

Anyway, i have been able to get it to work in a clunky kind of way.

 

It consist of 2 flows

 

Flow 1 - Triggered form PowerApps, Send an email to an O365 mailbox, Set attachment to peninput.image set subject to last ID in your sharepoint list.

 

This will send an email to the specified account with an attachment of your peninput, which you can open fine and see as an image.

 

Next step is to build a flow to look at that inbox and when a new item arrives, take the attachment and save it in your sharepoint list (Add an Attachment Flow) against the ID mentioned in the subject line of the email.

 

This will give you an image file of your signature against a sharepoint item, there is a slight delay in the signature coming in as flow has to wait for the email to arrive before adding it.

 

Its a bit clunky, but in my testing so far it seems to work reliably. I am rolling the app out to a wider group of people this week, so i will see how things work in a real world environment.

 

 

 

Thanks, @rockonron, appreciate it, will try that this week!

Hi @v-xida-msft

 

Will try this one as well, thanks!

Hi, Do we have working copy or steps available to follow. Regards Sri

I will pull together our process and post here, although this maybe next week before i can get to it.

Hey Ron

@rockonron Thanks so much for all of your detailed outlines, by chance have you been able to finalize the Flow that allows a user to save that pen input.?If so any insight or a snippet of the flow coding would be amazing. Thanks so much

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/add-images-pictures-audio-video

 

This one where they put the pen input into excel works good. I just haven't decided what would be good to do with it after that..lol.

 

I have seen some references to Microsoft adding the ability to put this in as an attachment which is why I put the work arounds to the back burner for now. I can make it view great in PowerApps and can email the signature fine too but I would like it to save as an image on my SharePoint list item in the attachments column. I have a few work arounds but none I like yet.

Microsoft Power Up program unveils new curriculum and more

  New engaging and cohesive Power Up curriculum The Microsoft Power Up Program – a self-paced upskilling program, launched in 2022 to help non-technical professionals gain marketable skills using the Microsoft Power Platform – takes learning to the next level with a cohesive video-based curriculum that spans only seven weeks. Recognizing the demand for multimedia content, we partnered with Microsoft MVPs Rory Neary and Charlie Phipps to create engaging videos that not only simplify complex concepts, but also make the learner experience more dynamic and immersive. Each course follows the same business through real-world scenarios with demos and hands-on exercises for learners to gain skills and build solutions using Power Apps, Power Automate and Power BI. This structured approach not only enhances comprehension but also equips learners with tangible skills that can be applied immediately in their professional endeavors. By focusing on key areas, the program has been shortened from 12 weeks to seven, saving valuable time without sacrificing quality. Special thanks go to Microsoft Power Platform advocates, April Dunnam and Renee Noble who shared their expertise and to Power Up Program champs who contributed with feedback and reviews over the last 1+ year to make this significant improvement.   Easy access to a comprehensive Development Environment In addition, the program now offers simplified and instant access to a comprehensive development environment for Power Up Program learners to explore and experiment with the Power Platform in a sandbox environment, fostering creativity and innovation.     Introducing App-In-A-Day (AIAD) workshops for Power Up learners As an added incentive, participants of the Microsoft Power Up Program can now sign up for partner-led “App in a Day” virtual workshops. These workshops, conducted by industry experts and Microsoft partners, provide invaluable insights and practical guidance to supplement the core curriculum. By attending these workshops, learners can gain deeper insights into application development and further enhance their skills in leveraging the Power Platform for business solutions. A big shout to our partners that are supporting the Power Up Program and delivering these AIAD workshops: Advaiya, Almato AG, Braintree, Kaispe, Koenig Solutions, PowerApps 911, Pragmatic Works, Smart Consulting.   These enhancements introduced to the Microsoft Power Up Program mark a significant milestone in the ongoing quest to empower individuals with the skills needed to thrive in today’s digital economy. By embracing video-based learning, streamlining the curriculum, and offering personalized experiences, the program continues to set new standards of excellence in virtual education.
