Here I gathered some resources from around the internet for quick access to payloads whenever needed.
Github - PayloadsAllTheThings
If you have ever thought of a great swiss army knife for exploitation this GitHub will be an amazing resource for any bug bounty hunter. Not only does it host one of the most comprehensive libraries of payloads that I've personally ever seen and you're welcome to prove me wrong if there is a better one, but it also explain in depth the types of payloads, and bugs to be exploited with the hosted techniques.
Addendum 1: Also the resource is maintained by a large following of experts within the Bug Bounty community. What I encourage you to do is if you find it useful, to SHARE your appreciation for all of their work when or if you will be able to be it kind words, money or spreading the information to other people as well!
Addendum 2: Anyone can contribute to this resource, and if at any point you grow into an expert that feels like giving back to the community, you can check there that you will be able to contribute to this resource in knowledge rather than in other ways receiving and giving back the love!
In addition to the amazing resource presented above I did find and craft from other sources as well some payloads I think deserve some attention as well.
